I am searching for siblings/ancestors of Capt John Frederic(k) ANDERSON b. 30 Dec. 1850 at Roslagen (some records show Stockholm) Sweden.He went to sea at 15, returned to Navigation School in Stockholm and received his sea captain papers in 1892; he immigrated to Canada, bacame a Naturalized Canadian Citizen in 1899, married in Victoria, B.C. in 1900, and navigated the West Coast of America until his death at sea 24 Dec. 1923.
His marriage documents show his mother's name as Anna, and his father's name is illegible. That's all the information available to date.
His name may have been Anglisized to John Frederick Anderson, possibly from Johan Frederic Andersson?
