There are some variations to the information I have found for some of the Hamson's listed in your post.

I have found various dates for Joseph Silvester Hamson's birth. His World War I registration card lists his birthday as 11 Jan 1883. On the 1900 census it lists his birthdate as Jan 1884.

Maude Hamson was born in 1889 according to her obituary and the 1900 census.

Joseph Smith Hamson was born in 1849 according to his obituary and the Utah Burial Index

Fedebion is Tededion according to the Utah Burial Records.

Jedidiah Mills Hamson was born 1858 according to the Utah Burial Index.

Boletta's last name is Mortensen according to her obituary and the Utah Burial Index. Her obituary also said she had 10 children.

I run across a lot of variations for family history. I am curious if the information you posted was passed down through your family or through other records.

I'm most curious about Tededion. His death record states that he died in 1875, but I can't find him listed on any census records with his family. If he lived til 1875 he should be on the 1860 and 1870 census, but he isn't. If anyone has more information about him, please contact me.
