Add to this that Galadriel wasn't even with those siblings from the beginning. From the start, Finarfin only had sons. Galadriel was created for LotR. When she was in place, she had to be worked into the old history somehow, and Finarfin finally got a daughter

Fëanor never had one, only all those boys
