I have a Dorland Losee that lived in the County of Prince Edward, District of Sophiasburg, Ontario in 1878. A son, Edmund Roblin Losee was born June 9, 1878 at that location.Ontario Vital Stat. birth reg. is 027376. Dorland was married to Sarah Dulmage. Edmund later married Isabella McLauchlin in Langdon, North Dakota on June 24, 1902.Isabella was the youngest sister of my grandfather Duncan McLauchlin. Let me know if this has put you on the right track for Dorland.
