Hi Lynn,
Thanks for contacting me! I still am in to family history...just go through on again/off again phases. I do know that Monemia is buried at St Mary Anne's Church in North East, Maryland. She died 15 Apr 1876 according to her grave marker. I don't know if you use findagrave.com, but that is an excellent resource and you will find a picture of her grave on there. You must also be a descendant of James' son Henry (as am I) if you are looking at the Kershaw and Simpers lines to. I have a wealth of information on both those lines and I will be happy to share. I will start by giving you access to my online trees. That should be a good start. Let me know how else I can help!
Thanks,
Ken
