Hi, You are the second person who has Catherine's(wife of William) maiden name as Dudderar, but no one has found proof.Did you find it in a record of some sort and if yes---where? William Dickensheets was the son of Christopher Dickensheets and his wife Catherine (Hannerman). They had eight children; John(to Ohio about 1803) Margaret(my ancestor) Catherine Susanna Elizabeth Ann (Hannah) Frederick (my ancestor-to Frederick Co., Md.) later Carroll Co.) Magdalene (Mary)
William died 3, January 1814.
I have a double line out of this family. The Dudderar family was also in Frederick Co., Maryland.They are all buried in St. Mary's United Church of Christ Cemetery in Silver Run.
