I am afraid we may be barking up the wrong tree.
I found John Adams and his family on the English 1891 census. I then found his wife and and some of his children on the Scottish 1901 census. Assuming that John had died I looked further and found the registration of his death (in Scotland) on 22 March 1899. On this it states that his mother's maiden name was Mary Ann Park so I don't think that Jane McNeilly has anything to do with him. I'll let you know if I find any more info.
