Northern Bay Church records at the LDS and there are not many Kennedy's in them.

Edward Kennedy wed to Mary McDonald Nov 26 1846
Terrence Kennedy wed to a Mary McDonald June 5 1870

I did not see any children for these couples.

Kennedy James & Alice Riggs child Bernard June 8 1877

Kennedy John & Ellen Woodfine child John May 30 1890
Kennedy John & Julia Dunn child Mary Joe Sept 3 1876
Kennedy Mary & Lawrence McDonald children Daniel Nov 5 1884 Mary Oct 6 1889
Kennedy Mary & James McDonald child Mary Sept 12 1886
Kennedy Mary & James Dunn children Patrick March 17 1878 Sarah Sept 6 1880
Kennedy Mary & Thomas Forristal children Bridget March 4 1875 , Nicholas July 1 1878

and that is it up to 1891 when the records end. I had seen lots in
Blackhead Methodist and the United Churches, but I wasn't copying
those records only the RC records for the area.
