Hi Huwcyn
How confident are you of your tree and how confident is your American DNA match with hers? Have you seen her tree? If not then see if she will send you a link to it (if online) or email you a GED.
If neither of you have been able to find parents for Ralph or Mary Ann then there's the possibility that one or other of them might be the illegitimate child of a soldier (I assume that the military were criss-crossing the Atlantic at that time).
If both of your trees stack up, and Ralph and Mary Ann aren't illegitimate, and we rule out the possibility that the same individual/couple didn't have families both sides of the Atlantic, then the MRCAs can't be any closer than the grandparents of your Ralph and her Mary Ann. That pushes the "cousinship" out beyond 6th cousin, so probably just coincidence.
Can I suggest that if you've not already done so, you do a free upload of your AncestryDNA results and tree to both FTDNA and GEDMatch, that way you will get matches to people who've tested with other companies and you'll also get some more analysis tools to play with.
Jane :-)
