I have just started to research a Cummins line that I found in Whitley Co., Indiana and find that they came from Delaware County, Ohio prior to the Indiana move. My gg grandfather Celum D. Cummins was born in Delaware Co, OH in 1839. His parents George Washington Cummins and Catherine Faulkner were born in NY and Ohio respectively. George and Catherine moved in Whitley Co, IN and they are burried there. It looks as though 8 of thier 9 children were born in Ohio. Celum married Frances Smith b. Indiana, in 1862 Whitley CO, IN. I'm curious if this Cummins family group might be related to your Cummins family?
