Thank you for all for your posts.
Yes I know Agnes died in 1908 and had a child Agnes in 1907 - I have no idea what happened to Agnes I just really hope that she went to live with good people. I know my Grandad was living with Roseanne Muldoon at 34 Milford Street in 1911 his Grandmother.
Due to Agnes's age at the date of her marriage to Martin that being approx. 29 years old I think the most close in age is Martin Lawlor born 2 Nov 1870 Thomastown. However his fathers occupation does not state Blacksmith so cannot be 100% this is correct and that's why I was trying to figure out how I can get a mother's name for him. The other two records I found around this time with a Father's name as John all seemed very young so I have ruled them out.
I think Martin remarried in Dublin in 1919 to Elizabeth Fitzpatrick also states his father as John Lawlor a blacksmith.
