It gets better

An update to my tentative dna success story about Amelia MILLAR of Kippen, Stirlingshire.

My Ancestry dna match has uploaded to GEDMatch.com, where I was  able to compare results with several other kits.
Bingo has become BINGO in as far as we do now know that yes, from my ancestral side of the fence that bit of shared dna has a common ancestral line at James HENDERSON and Amelia MILLAR between the extended HENDERSON/MILLAR family kits I can compare, so the shared anecstry with my match is somewhere back up from that couple - and looks unlikely to be the HENDERSON side.

Looking good that the connection is to his David MILLAR and Elizabeth CHRYSTAL - but more work needed to confirm it fully.
As he has also transferred to FamilyTreeDNA, we should have more data to work with shortly.

Love to hear from anyone recognising this couple as their ancestors and has either already undertaken dna testing, or is willing to join in the fun, or has research to share.

This really is the closest I've come in 40+ years to finding out something concrete about Amelia MILLAR's ancestry.
