Hi fguthrie,
It is getting stranger--
Done a search on SP for children of William Burnside and Is*bel* Hood for whole of Scotland from 1553 to 1854, came back with 1 result, James, christened 15 June 1819 at Garvald , East Lothian not far from Bolton, East Lothian. This is not on IGI
On the 1881 census at 35 Renfrew Street, Bltyhswood, Glasgow Barony
John Burns 48 b 1833 Bolton East Lothian Occ Carter
Hannah Burns 45 b 1836 England
William Burns 18 b 1863 England
Hannah Burns 14 b 1867 Glasgow
Sarah Burns 11 b 1870 Glasgow
John Burns 9 b 1872 Glasgow.
Apart from slight age differences, big one is, John is from Bolton , East Lothian, a bit too much of a co-incidence
