I have found some more info on my Kelly line, a birth order but I still need some help

James Thomas Kelly born 1866 to Stephen and Mary Kelly IOM
Married Mary Frances Egan in 1889 at Wirral Civil registry

Children:
Violet Kelly bn 1889
William Stephen Kelly bn1892
Agnes Eileen Kelly bn1895
Mary Margaret Kelly bn1896
James Kelly bn1898
Monica Kelly bn1899
Norah Kelly bn 1900
Clara Alice Kelly bn 1908

I know that this family were on the Island before Clara was born so they might have been there for the 1901 census. I can't find them on the UK cansus and I know where they lived in Seacombe, pre IOM move.

What I am trying to discover is Mary Frances Kelly nee Egan's place of birth, I know that one of her sisters was born in Birkenhead but we have been told that Mary Frances was born in Ireland.

Any help would be great
Kind regards
