We are trying to find information on our grandmother's sister, Sara Koelman. We believe her married name may have been Kuim and that she may have had a son Keese Kuim. We have found her birth record. She was born October 18, 1899 in Haarlemmermeer. Her mother's was Catharina Elisabeth Onkenhout and her Father was Gerrit Koelman and that is all We have been able to find out about her. We are looking for her marriage and death records. If anyone has any information it will be greatly appreciated.
