They had a son born in Coopenhagen on 11-8-1889.His name was Arthur Edholm.He married an Odgaard, Else Christine Kristensen born 2-27-1891 her parents were Christian and Else. Karl and Johanna also had one son name unsure, Lenis and Ruth and Edith.Chrstian and Else had the following children Magaus, Anders, Christpamor, Ellen and Marie.That is all I know about the family expect the Odgaards lived in Nor Korben Mos.My mother Else (Elsie) Johanne Edholm was born in Denmark April 8th, 1918. She went to school in Nor Korben Mos until she was 9 years old.She had a brother name Eric Edholm and a sister who only live 6 weeks named Ingeborg.

Spelling of some things may be wrong.I hope some one can help me find my past.
