I am new to your list. I am researching CONRAD STAMM (died in 1883 in Beaver Co. - I have a copy of his will). I am trying to prove (or not) that his daughter MARY ANN is my gg grandmother. My Mary was born around 1846 in PA. Married JOHN ANDREW KOONTZ, they had 3 children SAMUEL, CORA, IRMA. John remarried, in 1881. We think Mary ann married a WILLIAM SHEELER but we really don't know what happened to her. Patty Coates
