John Gaynor of Ballintue, Ballinacargy married to Ellen Egan

I am looking for any connection with an Ellen Egan, daughter of Michael Egan and Lucinda Maynes who married a John Gaynor. Son of James Gaynor on 31 July 1873. They were from Ballynacargy, Westmeath but Ellen was baptised in Glasgow, Scotland 23 Feb 1854. Ellens brothers Michael and William Egan and mother Lucinda Maynes migrated to Australia and William was my great grandfather.

I am speculating from certificates online from Irish Genealogy Civil Records that the children of Ellen and John Gaynor were James Gaynor son born 17 June 1885,

Twin daughters Kate and Ellen born 6 Apr 1888, with 15 month old Ellen Gaynor dying 5 July 1899,

William Gaynor born 2 Aug 1892 who died 18 July 1916 as a bachelor

Patrick Gaynor born 11 Apr 1895 a postman who died possibly 11 Feb 1951 as a bachelor

It appears this family was living at Ballintue, Kilbixy on 1901 Census which shows that Ellen was born in Scotland where the Ellen Egan I am searching for was born. The 1911 census shows a granddaughter Mary Gaynor, granddaughter also living with them at same place but I have not been able to find a record of her birth in Dublin City. I believe John Gaynor died 12 Jan 1913 and wife Ellen died 18 July 1927 at Ballintue.

Hopefully there are descendants either of a Catherine Gaynor ora Mary Gaynor who may recognize these names and dates and be willing to give me some information. Thank You Marie

Michael Egan born 24 Mar 1877 with Lucy Egan witness (possibly the grandmother)
