I am from another line of Raaps all of whom with the last name Raap has died off from what I can tell. I am hitting many brick walls. My mother was Kathleen Alta Raap. Her father was Irvin Leonard Raap. his parents were Louis Raap b jan 1867 d about 1954 Mamie or Marie Gerlach b jul 1869 d 1900. This couple was born in Baltimore. Marie's Mother Mary unknown Gerlach emigrated from bavaria in 1848 when she was 3. According to the US census, she was Married to a John Gerlach who was born in 1832 in Prussia. If you have any other information on this line, let me know.
