Apologies for delayed response - out of e-mail contact last week.
Thanks for researching this. Is there any record of children for Albert & Dina ?? Or of his death ?? In the 1900 census for Norway, Dina is back in Stavanger, occupation given as seamstress, and said to be living on "country's welfare, Ireland". Moreover she is using the surname "Hadland", the farm on which her father Gabriel Gundersen Hadland was born.
I didn't know Alexander had a middle name Samuel. Its not on his baptism record - not a common Norwegian name.
Familysearch has other children for Alexander & Mary, including Sigvart - the name of his younger brother who married my grandmother and thus convinces me this is the right match. I found baptism records for Nathaniel & Sigvart. From 1911 census, it looks like only Jinnater/Janet and Mary survived into adulthood. Are you able to find any further details of them, including any death record for Alexander or Mary.
