Don't know whether there is any connection here but my great great grandmother, Margaret Gregan, was born in 1813 in WestMeath. Her husband was William Coghlan born Co. Carlow in 1812. On the English 1871 they were living in Manchester with their family (all the children having been born in Manchester). There was also a niece, Margaret Coghlan staying with them. She would have been born around 1852 in Co. Carlow. They also had a daughter called Margaret but she was born in Manchester around 1846.
