M Thompson, I read with interest your surname list on the PA-Northumberland mailing list. I recognize 3 surnames....Garman, Wertz and Kerstetter. I have a (Mary) Catherine Garman that has been rather elusive. The information I have is that John Houseworth married a (Mary) Catherine Garman or Kryder. I am uncertain which name is a previous married name and which is her maiden name. I do not know her date of birth or death. I only know that she was born in PA and probably died in Snyder County, PA. This information comes from the Portrait and Biographical Record of Berrien and Cass Counties, Michigan. This biography indicates that (Mary) Catharine Garman Housewerth died at the age of 60 years in Snyder County, Pennsylvania. Her husband John Houseworth was born about 1800. His first known child was born about September 1824. There is a gap of 10 years before the next child is born and this child is named Henry Garman Houseworth, hence I believe Garman to be her maiden name. I believe that John had one child from a previous marriage and then he married (Mary) Catherine and that their first child is born in 1834. Plenty of Wertz. Kerstetters are in my extended family - not doing a lot of research there yet. All three of these lines came to Berrien County, Michigan from PA. I'm hoping you can shed some light on (Mary) Catherine. I believe she used Catherine and not Mary, but I've found info that indicates her first name was Mary. Thanks for any help you can provide.
