There is nothing that shows the relationship between Ana and Elsie or that they even lived at the same time. And there is nothing saying they are daughters of Clovis either. Unfortunately the only firm fact is that Clovis bray II is clovis' son. Rest could be nieces, daughters, grandchildren, etc Elsie has been a potential candidate only because she is a bray (whose family lineage helped create exos) and the flavor text on the ship eon trespass. Could be, but nothing solid
