The info I have is:
James Butler was born at 1 Mason street, Grove Street, Deptford on the 18th feb 1868. John Butler and Elizabeth Butler nee Carroll.
I found a James Butler in 1871 in Deptford but he was a nurse child. and a John Butler living near by as unmarried, brick labourer from Ireland.
I can't find anything in 1881.
Then found a James Butler in 1891 living with his brother John Butler (born 1844 from Ireland again brick labourer ) I think this is his father.
in 1901 he is then living with his wife Hannah Maria Hanlon, his father John and their children. He was a comedian act.
can't find 1911 but did find his wife and children. so maybe he was working away.
Then found him in 1939 living on his own in Bethnal Green, retired musical hall act.
I know about his children and a little able his wife's family. But nothing at all with Elizabeth Carroll his mother (though there is a census in 1861 where an Elizabeth is living with her father John, Mother Eliza and sister Mary in deptford but there are no other leads).
thank you both so much for your interest in helping me.
Kind regards
