Hello again
Having looked further back in the records, it appears that some of the Regans were in Southport in 1849 although I can't find them on the 1851 census
1st Dec 1859 Birth
Mary Mulvaney
Parents Joseph Mulvaney and Bridget Brohony
Witnesses John Regan and Elizabeth Haigh
30th July 1849 Birth
Thomas Horan
Parents Michael Horan and Bridget Gill
Witnesses James Regan and Bridget O'Connell
4 September 1851 Birth
Sarah Regan
Parents James Regan and Sarah Keregan
Witnesses John Garry and Ann Brohony
Interestingly, to tie in with the Horan/Regan connection above, I found the following:
5th Nov 1892 Marriage
James Horan - father Martin Regan!! Living in Little Ireland
Catherine Gannon, father Michael Gannon. 135 St. Luke's Grove, Southport
Witnesses: Mary and Bartholomew Cairns, 13 St. Luke's Grove.
If I find any more I will let you know
