I don't think that Kaguya's maro are her eybrows, given how big and high up on her forehead they are. There are some distinct visual similarities between Kaguya, Indra, and Kimimaro.

Obviously, anything at this point is purely speculation, but I think there's a pretty good chance that the Hagoromo and Kaguya clans have some sort of ancestral connection to Kaguya, either through blood, marriage, or feudal obligation. The same is likely true for several other clans in the series.

However, until something overt is mentioned in an official source, there's really not much point in discussing it.
