Thank you once again, as far as I can tell James Swanson/Mary Clear had eight children, five of whom were born Wexford, Elizabeth (1881) James (1884 my wife's grandfather) Mary Anne (1886, Laura's G.Grandmother) John Patrick and William as you have pointed out. William married Elizabeth Martin in Liverpool also in 1914 and together had 8 children by 1932. James and Mary had three more children in Liverpool, Sarah (1892) Patrick (b.1894-d.1895) and George (b.1897)
There are more Swansons in Liverpool about this time and I suspect they will also have Wexford links, if so I would assume they are part of the wider family, though as yet the reason for the move isn't clear.
Again many thanks for your assistance.
