I am looking for information particularly the birth date of Marritje Johanna (Maria) Koelman. I know she was born in 1909 and died in January 23 1910. I found her death record but am unable to find her birth record. Her mother was Catharina Elisabeth Onkenhout (my great grandmother) born October 6 1873 in Haarlemmermeer, Noord-Holland, Netherlands who died August 19 1909 in Purmer, Purmerend, Noord-Holland, Netherlands. Her father was Gerrit Koelman. He was born in 1870 I believe, and died May 30 1943 in Winterswijk, Gelderland, Netherlands. I have been unable to find his birth record also.
