I have just discovered four more children of Joseph McGAW and Christian (Christina) ANDERSON in Paisley, Renfrewshire, Scotland, after knowing of only one son Robert.
All ages are taken off the 1851 Census and are approximate. John b 1837, Elizabeth b 1843, Christina b 1846 and Andrew b 1849. The family belonged to a breakaway group of the Church of Scotland, the United Secession, so births/christenings are not on OPR's.
If anyone sees a connection, please contact me. I have lots of information on Robert's descendants to share.
