I cannot find a Charles Cowin, but i did find an Isabel Cowin in my ancestory. She was the Sister of John Thomas Cowin, daughter of John Cowin and Margaret Cowle. I followed that vein and found that Margaret Cowle's parents were John Cowle and Margaret Killey(Kelly Perhaps?). Going further down the vein, John Cowle's parents were Charles Cowle, and Isabel Kneal. I still couldnt find any proof to the name charlotte.
I did read somewhere that the Cowan/Cowin/Cowle, were sometimes confused or inter-used, as the case may be.
But in my studies, Charles Cowle DOES Go back to the Isle of Man. he was born Mar. 6 1720-21.Died Est. 1771-1813. and Isabel, born Mar 5, 1740-1741, died Est. 1772-1835. However, there was only one child that i can find. He was John Cowle B.Feb 26, 1769, D Est. 1801. Let me know if this info helps. haha, or does it confuse? :) E-mail me at CFisk101@aol.com
