Hi, I have no specific information on your Elisha Croucher, but I am looking for the same name in Sittingborne, Kent England Abt. 1800 father of Horace b 1832. This family stayed in England until abut 1910 when George and his family came to Canada.
What i wanted to tell you is that there is another Croucher group at Ancestry.com. You might check there for help.http://www.familyhistory.com/messages/Messages.asp?id=9341
Good luck in your hunt. If you ever get back to England, get in touch, my husband and you might end up being related.
