Hi Sandy, I'm also researching the Cade/Kellar lines.David & Sarah are my 2nd Great-Grandparents and I have some information on the generations following them.You can email me and I'll be happy to provide you with more information.I'm in the process of updating my website, but you can see some information on it currently at www.oz.net/~blueboyz/genealog.htm
Looking forward to hearing from you. Chris
Sarah Cade married David Keller born abt. 1827 and died 1874, Sheffield Twp, L&A Co, Ontario. Looking for details re: their children.
