Thomas Kilroe and Jane Berry

I am trying to find out more about THOMAS KILROE, b Fohanagh between 1798 and 1807.  Can anyone suggest where I could look to find a birth record, if one exists, and to find out who his parents were.

He married Jane Berry  I have no info when or where they were married, and know nothing about Jane.

Unsourced information is that they had a daughter in1838. THen a son Thomas, who was born in Edinburgh on 3 April 1839  (or 1841).  THomas Snr was apparently in the army.  I can't find any enlistment record, and wonder why he joined up.

Four more  children: Ellen 1840, Julia Sept 1842, Caroline 1850 and Matilda 1850.

Thomas was sent to South Africa with the 7th Dragoon Guards Sailed 10 April, arrived in Cape Town 14 July. I can't find any passenger lists or shipping records for these dates.

I suspect he was one of 38 who left the unit when it was about to return to the UK in 1848, and might have been employed as a blacksmith in Grahamstown

He died in Burghersdorp in 1854.

The South African Commercial Advertiser Tuesday 10 October 1854

DEATHS Sept 18: At Burghersdorp, in his 56th year, Thomas KILROE, blacksmith, formerly of Fohanagh, County Galway, Ireland. M.I.P.

I would really like to know more about THOMAS KILROE's and JANE BERRY's Irish ancestry, and would appreciate any assistance or suggestions.

Many thanks
