Hi! could someone help with these two similar but not the same person profiles?

Question

There are sources for a Martha Blair and sources for a Mary Blair, with different fathers, (I put the sources that Mary's father is Robert). Then I found this study on this very confusion of the two woman named Blair by Arthur B. Broddus which concludes that Mary is Martha's niece and seems like good research, as he lists many sources. But then he shoots down the sources for the father as Robert. This is a bit over my head so any help appreciated!

Answer 1

This source shows family.

Martha maybe used the name Mary?

Hi!

Thanks! But Find a Grave lists Martha's family, and not 2nd wife Mary's family. Mary appears to have a different father. I am hoping someone can help sort out the sources!
