Susan, if you haven't found data on your Adison Calvert 1860 or 70, email me direct at email@example.com and let me go over what all I have found in the past few weeks on this man.I have data on him in 1860, 70 and 80, as well as other data. There is an Addison P (Park) and possibly Addison Mansfield, Addison Russell and Addison B, or A. B. CALVERT.I do not know if they eventually will all tie together or not.I am sure Addison Mansfield ties to Mansfield Calvert, Addison Russell Calvert 'may' tie to John D. and Jane (Russell) Calvert who removed to Barren Co KY in early 1800's, and I don't know about A. B. (perhaps Addison Bernard) Calvert.He 'may' tie to George B (perhaps Bernard) Calvert in KY in mid-1800's.
If anyone has further data to share on any of the above lines, posts it. Thanks!
