It was typical for first-generation Germanic immigrants and their children to marry other first-generation Germanic immigrants. Very rarely you'll find a marriage to a Scot. English people not at all. If there's a Carr marriage at this time I'd be quite surprised unless it's an anglicization of a Germanic surname.
Screenshot posts can't be added to discussions; you can perhaps add this to a profile as a source though.
I see your relationship. You are claiming a Germanic family that arrived in the mid-1700s intermarried with a New England family present since the mid-1600's? That's quite a claim.
If this is Georg Kirschner himself, it's simply not possible; he arrived in Philadelphia, and the Carrs of New England didn't leave New England until well after Georg died.
Not Georg Kirschner himself, his sons and daughters. The Kerr family and Kirschners are well documented as established migrating from Germany to Switzerland, to Netherland and other places, the documentation of these immigrants into America would be anywhere from 1500 to 1700. The Kerr/Carr family of german descent should have documentation of their marriages. The Kerr/Carr I am researching have established landings from south of Florida, to Canada, and North of that. I have done some amount of research on the travels of the Carr/Kerr families from Germany/Palatinate and other European places
