Hi!
I've just found your post from 2004, so I don't know if you're still looking for information, but I have family information on Cheshire Threadgolds including George Threadgold who I didn't realise had emigrated to NY! His father was my Great x 4 grandfather, and his wife was Ellen Taylor,married on 23rd Jan 1816, as long as we have the same person in mind!! If you're still interested, I'd be happy to help.
