Ikshvaku

Did know they have mythological ancestries on here? Some even say it on them. Kinda wish those weren't on here, but not going to fight that battle as it would be an excuse to also get rid of the Bibical ones as well.

Yes, some people have entered the ancestries from the Vedas.

Like in the Biblical tree, there's traditions that link existing people to those traditions, and we have no bright line that lets us say "this is documentation, that is legend". So we should cut the lines where there's no evidence, and leave them in place where there are citable references.

https://en.wikipedia.org/wiki/Ikshvaku_dynasty shows a dynasty of 148 generations, ending in the year 362 BCE, so 167th grandfather seems a little short if that's the tradition that has been entered.
