Ok, according to my father's research, his mother was Cetka Mitvak from same region Peter was born in and his father was Francoise Dulin from France. Also, his SS# was 116-07-6819. However, his birth dates conflict: my father's record indicates 8/26/1888. His scoial security record shows 12/14/1886, and he even writes 1886 and 1887 as his birth dates on registration cards and naturalization papers. The manifest from the KOLN ship destined to Baltimore from Bremen Germany around 1913 shows both his parent's birthplaces as 'SLOVAKLAND' and it did not show anyone who was left behind.
