I'm following my Crebbin line back and in 1822 John Crebbin married a Jane Karran in Rushen. Date would be 2/12 or 2/02. I know of one son, Thomas Crebbin born in 1832. John was a Blacksmith by trade.

Do you have any other info on this family from your Karran tree ?

I suspect Jane had brother William, as Thomas is listed in a later census as working for his uncle, William Karran
