We tend to think Solomon W. Dodd was the son of Solomon Dodd Sr. Solomon Jr. was born abt 1778 in Delaware according to the 1850 census of Monday twnshp, Perry County Ohio. We based This connection on the below record (probably from the Sussex County recorders office):
Book F P. 225 G.79
1796.11.23 Solomon Dodd died in intestate leaving a widow Hannah (Carey?) and 11 children.
Jane Steel Married Willima Steel 1783.9.11
Keziah Wilson Married Thomas Wilson 1784.3.2
Solomon W. Dodd married Rhoda Reed in Farifield County Ohio on July 2 1816. Soon after that, Fairfield County was split up and Perry County was formed as a result. It's likley that Solomon's sisters (Hannah and Comfort) married into the same Reed family. There was a James and Rhoda Donovan Reed that had a daugter named Rhoda Reed in Sussex Delaware. Not sure if it's the same Rhoda.
I have seen some records that indicate that this Solomon W. Dodd was Solomon Wesley Dodd that had a father Jonathan Dodd and Mother Jemima. I don't think that is correct because Jonathan goes back to the New Jersey Dodd's. This Solomon was clearly from Delaware according to the 1850 census. At least two of Solomon's brothers also had son's named Solomon (George and Nathan). And Solomon W. Dodd also had a son named Solomon...It can be confusing.
Hope this helps,
