It is possible, Don, that I have some information to add to your family history - and perhaps you to mine... This Henry (and Bertha) sounds like my 2nd-great-grandparents.When my grandmother died in 1985 I lucked into a copy of a letter written, in 1984, by Edna Anderson (Ole's niece maybe?) to her granddaugher Karina (whom I have never met)...This letter refers to many of the relatives who settled in Summit, South Dakota, and who were born and died in (near) Albee and Milbank.I have the names (and many dates) of all 9 children, including the baby that was born and died in 1886. My great grandmother, Mary Engebretson (Henry and Bertha's daughter), married John Olson, who later moved to Canada and changed his name to Orr... The dates you have given for Henry and Bertha match with mine - so this may be a 'hit'!Although I have Ole as being born in 1871, but you say he died in Minot ND in 1875 (did you mean 1975?) I hope we have a connection!
