''Chapter One - rural to industrial
Mary Colston - My father-in-law, Jeremiah Connolly, was killed at the iron works at the Forge, Maesteg in 1877, leaving a wife and six children. Mrs Connolly had no compensation and had to go to work at the iron works earning ten shillings (50p) per week. She was there for five years until the works closed. She was then given parish relief of five shillings (25p) per week.''
Apart from the year of death being out by ten years, and possibly adding a sixth child (you seem to have five), I wonder if this is your ancestor?
Little bit about Maesteg Row:
''There were lodgers in every house in Maesteg Row when I was a child. At the top of the street was a long flat raised stone seat known as the 'rodney stone' which could seat about 12 people. This was a common meeting place for the residents who were nearly all Irish people. We were a close knit community and the street was also known as ''paddy's arcade''.
And the book also confirms that Maesteg Row was formally known as Company Row - I suspect it is the street I have pointed out to you, although from speaking to my grandmother, it has changed considerably since she was a child.
Sadly, my eyes are burning after eight hours in front of the computer screen in work, several hours watching the TV, and now pulling all this together after the mrs FINALLY got off the computer - hope some of this is useful - more than happy to see what else I can find if you provide the info - my time, sadly, is limited, but if you can locate a grave (or give me an idea where they're buried), I can certainly attempt to locate it and e-mail a photo across. if I get time, I'll get a photo of Maesteg Row for you as well.
