My Gt Grandfather John McHugh born Co Mayo 1854/5 wed Jane Brannen (late Scott) 1895 in Wigan and they are both widowed . 
Now for ages I have looked for marriage info on John and found a maybe . I am using Lancashire  B.M.D. , she is Mary Sweeney from Leigh , the marriage is in 1874 Leigh and a death in 1895 when she was 38 . 
I have also found a birth in Leigh in 1858 with mother`s maiden name of Conlon but not anywhere else to confirm .
This could well be John on 1901 & 1891 census with mother in law Bridget SWEENEY and married to Mary
