Hi Beth,
You said you had more RYDER information, do you know who parents of Wilson RYDER were ? Pretty sure they connect to mine, since mine are all over Yarmouth & Barnstable County, Massachusetts.
I have 1850, 1870 & 1880 Census info on both Luther & Wilson if you don't have it and need it.

My line:
1. Ebenezer RYDER & Experience (HALL)[Mercy RYDER line]
2. John RYDER & Susannah (CROWELL)[parents of Mercy]
3. Edward RYDER & Mercy RYDER
4. Edward & Ruth S. (Covel) RYDER
5. Almeda S. (RYDER) & William H. COLLINS
6. Ada F. (COLLINS) & Charles W. HARDING
7. George Henry HARDING & Nellie Ruth (HOPKINS)
8. Hope Lillian (HARDING)HOBBS, my late mother.

I have not found parents of Edward husband of Mercy RYDER yet.

Thanks
