I'm not sure you got the info you were looking for but, I have quite a lot on this family. I'm not sure you are aware of it but there were more than 3 sons. In addition to Leman, Noah & William, there were 2 daughters, Margaret and Fanny and a son, John.
Please contact me at PixieSchultz@verizon.net
for more info. I would be happy to share. Also, you can review my tree on ancestry.
Hope to talk to you in the near future.
