Rathvilla Parish Registers - WHELAN

[The Engineer]

My wife's 2nd great grandfather has recently been discovered to be a John WHELAN, born in Rathvilla about 1827.  In the 1861 census he appears at the 5th Royal Irish Dragoon's barracks at Aldershot, a private, aged 34.

His wife is Fanny BEEBY aged 25, born in Castle Donington, Leicestershire.  They have one child, my wife's great-grandmother, Mary Ann WHELAN aged 8 months.  I have Fanny's maiden name from the birth certificate for Mary Ann, which I have already obtained.

I am trying to find any more information on John WHELAN, especially his parentage and possible siblings.  If anyone has the means to assist with this search I'd be most appreciative!

Many thanks,
Garry Brookes
