Parish Record for marriage

  
Church Marriage Gaynor Patt   1850 Co. Kildare Allen RC
Church Marriage Grey Margaret 1850 Co. Kildare Allen RC

15th April 1850 - Allen RC  Co. Kildare.

Address for both are Grange, Allen, Co. Kildare.
Witness: Christopher Monaghan & Mary Couglan.
No fathers names recorded.  

Margaret & Patrick's children were:

Catharine Gaynor, b.1851, baptised Co.Kildare Allen RC
Bartholomew Gaynor, b.1853, baptised Co.Kildare Allen RC
John Gaynor, b.1856, baptised Co.Kildare Allen RC
Elizabeth Gaynor, b.1857, baptised Co.Kildare Kill RC
James Gaynor, b.1858, baptised Co.Kildare Allen RC
Patrick Gaynor, b.1861, baptised Co.Kildare Monasterevin RC
Christopher Gaynor, b.1865, baptised Co.Kildare Monasterevin RC
Henry Gaynor, b.1868, baptised Co.Kildare Monasterevin RC

I believe all these children to be correct. Has yet to be confirmed by full parish records for any of them other then Henry (IGI) and James (full record obtained). All of the above come up in the parish indexes with father named Patrick in the same time frame and parishes as Henry & James.
