I have a Samuel Garis born 11/17/1824, married to Susan Maria Eichman on 10/1/1846, Northampton County.
Their children were;
Mary Alice (my ggrandmother born 5/23/1847)
William Edwin, born 9/26/1849
Irvin Henry, born 9/7/1851
Helen Maria, born 2/21/1856
Cornelius "Charles" Weygandt/Garis, born 12/19/1853
David Valentine, born 3/4/1862
I believe that all of the children were born in Easton, Pa.
Does anything match?
