A great-aunt of mine was briefly married to Denis Sweeney, born Dumbarton 1885, died Motherwell 1915, he was the eldest son of Charles Sweeney and Mary Moan. Charles was the son of Denis Sweeney and Mary Boyle.
Charles and Mary Moan had at least 5 other children, 4 daughters,
They were - Ann Jane born 1887 Dumbarton.
Mary, born about 1893 Philadelphia USA.
Sarah, born about 1897, Jersey, USA.
Agnes, born 1899, Dumbarton, Dunbartonshire.
There was a son, I can't remember his name (but I'll find out), it may have been Charles, he is buried in Motherwell with his brother Denis and my gt-aunt, as far as I can remember he died in Dumbarton in the 1930s.
Denis Sweeney and my gt-aunt never had children, he spent much of his married life confined to hospital with tuberculosis.
