Several things. These are direct ancestors for me but all the dots don't connect on Geni at this point, so I was going to work on that and noticed a few things:
1) These are duplicates I'm unable to merge:
2) The last name is Robins / Robbins. It's well-documented on https://www.wikitree.com/wiki/Robins-56 and other sites
3) The name Clarke is NOT part of her father Obedience's name or that of this Margaret's name other than the fact that she was married to a Clarke before she married William Waters. So her father's name was not Obedience Clarke Robins, as one tree shows, and her correct name would be Margaret (Robins) Clarke / Waters.
https://www.wikitree.com/wiki/Robins-56 - and according to the info on Wiki, her 2nd husband William Waters was her step-brother.
Margaret (Robins) Waters' Find-a-Grave page doesn't mention a first marriage to the Clarke husband. Only her Wiki page mentions him and says that is 'tradition', that there is no documentation.
One tree has her mother as Margaret Parker whereas most sites state her maiden name was unknown. If someone has sources for the maiden name Parker, please share that info her About section.

I'm not a manager on any of the three profiles for her and am unable to merge the two listed, so I'm hoping someone can fix the names, add the notes, and do the merges and then I continue working on down from her daughter Susannah (Waters) Terrell that my branch is from to get my line connected.
Thanks in advance for any assistance.
