My mother's grandmother's maiden name was Esther Marie Charche. She had lived in Annapolis, MD. I myself am a resident of Baltimore.
Esther Marie married a DeForrest Caradine Leech Sr.
I am unsure as to her birthdate or deathdate, I do know that DC Leech died in 1985. So my guess was that Esther (my great grandmother) had been born around 1920 or so. I know this is a little later than your 1700's, but you never know, there could be a connection. I am trying to find out more info, and I will update you if I come across anything significant. Thanks for the post. Good luck with your search.
