I am not a professional Genealogist, but I have some time and like to help. Here are some leads:
1. the Chenoweth's are extremely well documented at
http://www.chenowethsite.com/ch7wwb1.htm2. Martindales are well documented also at the above and at:
Familysearch.org
3. The Guyer's were an allied family of the Cady and Martindale lines and I ave not done much research. See Peru,IN (Miami County) where they were in abundance in the 1840's.
4. I am in the Cady line. Henry Lemming Cady line is the largest branch (Miami Co,IN). My line is his youngest brother James Curtis Cady. I have been in contact with a cousin in Henry's line who could be of help if you need it. Send me your email address to
Jcady622@aol.com I have a list of six generations at Geneaolgy.com/Cady which I have updated and revised. It is only a list with Birth and Dead dates.
