I am looking for information on a Joseph KERR and his wife Elizabeth RUSSELL. They are mentioned in a letter I have a copy of wriiten by an ancestor James KERR CAUGHEY from Medina, Ohio to his brother John CAUGHEY Jr. in Barttownship, Lancaster, PA. The letter is dated 15 May 1837.
I believe that Joseph KERR may be the brother of my 4 g grandmother Elizabeth KERR, as James refers to them as Uncle Joseph and Aunt KERR.
Any help is appreciated.
