Searching for the dad of Johanna Durr / Derr (aka Anna Durr / Derr) born Jan 1866 according to 1900 census.
Anna would be born in Northumberland Co., possibly Schuylkill Co.
1910 census she's living with her mother, Matilda Kendrick. Her parents were born in PA.
She married Henry Youst.
More info on her on my site:
http://www.searchtrees.com/tree/13615.htmI figure she must be a branch off the Durrs of Lehigh County who migrated to Northumberland and died there.
