Thyrza Jenkinson Sligo1842 Nottingham England Godward

My Gt Grandmother Thyrza Jenkinson born 1842 Co Sligo Ireland. Married Henry Godward born Worksop Notts 1845. Married at St Bartholomews Nottingham 21st November 1865. Her fathers name, witness on the marriage certificate looks like Galilio. the address is Millstone Place Nottingham, where Thyrza and Henry lived for a number of years. However, it is information I require on Thyrza previous to her marriage. I know she worked as a cook for the priests at St Bartholomews, but when did she arrive in England, and where in Sligo did she originate. Any Help appreciated.
