Margaret Train, b.1630, MD; md. Andrew Caldwell
I am not researching these peopl, however, I do have Caldwell ancestors, and have seen this information in other books:
From the Cox genealogy on the internet:
"Margaret Train was born in 1680 in Somerset Co., MD.She married Andrew Caldwell, b. 1675 in Kent Co., DE.He died in March 1750/1 in Kent Co., Delaware."
They had at least one child, Agness "Anne" Caldwell.
