Looking for any information on Frederick Gravelle. He was born 25 March 1881 in Ottawa Ontario, son of Francois Xavier Gravelle and Marie A. A. Lamirand. Francois and Marie married about 1869, location unknown. Francois Xavier was born 2 May 1852 in Chelsea Quebec, and died 20 February 1915 in Carleton Ontario, and was the son of Joseph Gravelle and Julia Parent.
Frederick Gravelle (born 1881) married Margaret Maud Sullivan 2 September 1902 in Brockville Ontario, and they were my husbands maternal grandparents.
My mother-in-law always said she was half French, half Irish and all Catholic. The info I do have I've found in the Drouin records, the Ontario French Catholic records, and Canadian census.
Any suggestions, leads, or info would be greatly appreciated.

Thank you,
Rhoda Blake-Hudson
