I can add another puzzle for you ............from ancestry, 1871 census john and ellen colligan have nephew, john colligan age 16 living with them........in 1881 census holytown, helen witten down (ellen colligan) has nephew john cooper living with her age 26 this nephew is Margaret colligan's son......Margaret was deserted by husband john cooper.......married him as margaret colvile.......in poor law records her parents are edward and ann............. also in a 1841 census for helen colligan, it possible margaret living with her then as well age 21...........this all from ancestry and following the hints to try and track people through the census.........i am sure i seen john and ellen/helen written down as colville/colvile and colvine as well, i will have to go back and check that though.............so going from this jumble of info, edward's family and john's family must be related somehow..............also interesting is there is an archibald colligan married to an ann cleland as well, but dont know if that little snippet is connected as yet....................good luck, i know i need it trying to figure all this out!
