I'm tying to find information on Fredrick Mitchell b.1866 in Canada,imagrated in 1867.He was living in Providence Rhode Island USA in 1920,he was listed as widowed and a boarder living with the family of Clarence R Mason.I would like to find proof of birth,name of parents and siblings,if VERY lucky and someone knows this african american Mitchell family,WHY they left Canada? Thanks for any info you can share!
