Hi,
I don't know if it is the right name,on the 1861 census for Stourbridge in Worcester Eng. it states that Thomas was born in Lathom Ireland,and his wife Ann (nee Reilly) was born in Jons Meath,Co. Meath,they were in Liverpool in the 1851 census with a son James who was born in Liverpool,Thomas was also in Liverpool in 1841 in lodgings.
I see that there's a place called Leitrum and wondered if that could be it.I think he came from Mayo but can't be certain,maybe you can throw some light on it
Regards Pat M
