Ellen Magill** (1885 Belfast-1949) m.(1902) James McManus
5. William Magill (1889 Belfast-1916)Haven't traced John Magill after 1901 (although he's likely the John Magill at witness in 1902 At Ellen Magill's marriage)
Both William and Edward didn't marry but Mary Elizabeth and Ellen did have families so possible some of them had children of their own.
