Main story, chapter 7: Where Jedi Master Jocasta Nu reinvents the Skywalker family history and their links with the Sith
Jocasta Nu held a sigh, taking in the massive chart stretching before her eyes, in Anakin best attempt of stylus-writing that was still chicken-scratch painful to decipher. There was more holes, question marks and closed lines than documented ones, but it was still large. Jocasta would have rather riffled through clerk-reports, but those were not common on Tatooine. Settling on the task, the Jedi Master started by the bottom: young Skywalker, not even a question mark or a line indicating he had another parent than Shmi. Considering the rumors flying around in the Temple, Jocasta could understand the absence, even if it put in doubt the whole chart. But then, Anakin conception wasn't exactly physical and Shmi had no way to identify a father, and may even think there was none.
Shmi herself did not know her father identity, but it was already established to be Ben Solo. Rey Skywalker was indicated as Allorey, which meant they could send another fruitless search or deem that she used nicknames and alias for most of her life and give up trying to track her travels. The rest matched Solo tale, up to Vader whose name was seemingly Owen Skywalker, wed to Tura Skywalker. As one of her parents bore the name Lars and the other followed the naming tradition of the Tusken clans, the name Skywalker came from her wedding. Owen himself inherited the name Skywalker from his mother Leia, rather than his father Biggs Darklighter which was strange as his two brothers bore their father surname. Jocasta would have liked using this chart to end the rumors about padawan Skywalker parentage, but a different surname may mean a different father so the opportunity was wasted. Leia bore neither her father or her mother name, but her grand-mother Koshré, like the name jumped a generation. Jocasta attributed this oddity to Tatooine naming traditions, on which records were scarce but complex. Strangely none of Koshré three brothers and two sisters bore the name Skywalker, unlike Koshré two aunts and her mother Allorey. Jocasta raised an eyebrow, seeing no progeny indicated for Koshré siblings, while one of her aunts, Beru, had a son by the name of Anakin Skywalker which was followed by a question mark. Jocasta guessed Shmi only thought to put Skywalkers and their direct progeny, but she could not exclude Koshré was the only one of Allorey's children to have children of her own.
Allorey and Beru mother was Cheni Skywalker, her husband indicated only as "offworlder", implying he did not leave his name behind. Jocasta eyebrows furrowed, seeing Cheni mother, Tura, wed to another Anakin Skywalker which she backtracked as her cousin twice removed. This Anakin mother was Shmi Skywalker and his father indicated as Tusken. Tura Skywalker was the great-granddaughter of another Koshré. In the same lapse of time nine individual directly related to the Skywalker did not bore their name. Her hypothesis of first generation non-Skywalker confirmed, she was still left with the mystery of why some members were called Skywalker and not others. Glimpsing toward the top of the family chart, she ascertained that every female Skywalker got her name from a limited list of nine names, all of which appeared in the first two generation, seventy-one generation ago discounting three gaps. Male names were more varied but still limited overtime to thirteen different names, and a few variation of those. A quick interrogation to Tatooine limited data base and Knight Sharad Hett reports made evident the names were common either amongst moisture farmers or Tusken, and most of the time in the two groups. Considering the top of the chart was mostly composed of Tusken, Jocasta was not surprised. Still, the names may have been very common, it was a strange coincidence over an hundred Skywalker all bore twenty-two names used at least three time each. And considering the three-quarter of the Skywalker were females, there was a lot of Koshré, Leia, Shmi, Tura, Cheni, Allorey, Beru, Anikka and Riam.
In fact, Jocasta could see her observations even more prominently amongst the Tusken clans, where members only had a first name, excepted an unbroken line of female Skywalker all loosely kin to each other. On the next segment male Skywalkers appeared, most of the time directly linked to female Skywalkers but thrice popping up unexpectedly, probably because Shmi had been unable to keep track of everybody – which Jocasta could forgive as she found Shmi memory about her ascendency properly awing. The Tusken seemed more prominent in the next segment, with only two male Skywalkers, and the Skywalkers starkly evident amongst the other names. Evidently, Skywalker meant more than a random name, it had a significance Jocasta was unaware of. And for Shmi to be able to remember all those names, she must have learnt the list like a mantra as a little girl, because she was orphaned early according to Mace. An hypothesis drifted in her mind, pushing her to track down Knight Kenobi and ascertain that while Solo referred to Ben as his son, he never explicitly named him Ben Solo, and often mentioned him as a Skywalker.
It proved nothing, but clues were accumulating to explain why the Skywalker name jumped erratically amongst a same family. Then, Jocasta checked the record and found Tatooine had never been visited by Seeker in the last thousand years, as it was not in Republic space, except one time. A human boy named Owen was brought amongst the Order. His surname wasn't Skywalker but the name appeared often in the chart and chances were slim that the one time a Seeker came to Tatooine he found a Force-sensitive child. Especially considering the absence of test-at-birth and record. The child was reasonably powerful with twelve thousand midichlorian per cell. Not exceptional like the current Skywalkers, but the higher the count, the lower the number of Jedi boasting it. Force-sensitivity, as a norm, was around two thousand and five hundred midichlorian per cell. Owen count placed him among the twentieth percentile of the Order. But while Force-sensitivity was not automatically inherited, test on parents always found at least one with above-the-norm count. A family inbreeding regularly would boost its midichlorian counts under the right conditions. It was an acknowledged fact from the time Jedi were permitted spouses and children that Force-sensitivity appearance was higher in Force-sensitive offspring than amongst children of non-Force-sensitive. And one the Sith were well aware as they never shied from having progeny. It was even the whole basis around the current Skywalker marital practices and the reason there were so many noble-born amongst the Order: limited partners pool previously historically selected. No one had ever determined the right conditions under which midichlorian counts augmented as generations passed, but something on Tatooine must have produced such a result. In fact Tatooine had something in common with Korriban, remembered suddenly Jocasta: harsh living conditions in which Force-sensitivity would be an evolutive advantage preciously cultivated. The Skywalker on Tatooine seemed to be following the projected steps of the Sith specie.
This thought led Jocasta to check another theory of Mace, against the average generation age for humans. Taking into account the gaps which must have lasted over five generations, for Shmi had a few times backtracked four in-between Skywalkers, it made for at least eighty-six generations which at an average of twenty-five years meant the first Skywalker must have lived roughly two thousand and one hundred fifty years ago. Factoring a human female could reliably have a child between fifteen and forty, the span of her arrival was between one thousand, two hundred and ninety years ago, and three thousands, four hundred forty years ago. Which was short for Empire-era Sith to have drifted to Tatooine, but possible considering male human fertility period and remanent of a broken Empire fleeing far from Republic Space. On the other hand, Sith from the last great war were a lot more probable.
Owen's father isn't Biggs Darklighter as he was born two years before his mother wedding but was raised by him, hence why Shmi put him alongside his half-brothers but with his mother surname.
