Hi Tom,

My wife's line is through Joseph's and Elizabeth's first son Frederick. His son Frederick George, and then his daughter Ellen Elizabeth who was my wife's grandmother.
I don't know whether you know but Joseph and Elizabeth and several of their children apparently became Mormons and emigrated to Salt Lake City Utah in the 1860's and 70's, so there's a whole line of Firkins over in the States!

Which line are you descended from?

Regards,
Terry
