Hi Adrian,
Thank you very much for your kindness.
I have been using Ancestry, Family Search, CPRD etc. There are lots of errors in FS and Ancestry.
My John Williamson was a tailor of Bunbury and married Mary Roycroft at Acton (near Nantwich) on 18 Jan 1798. He was buried at Bunbury 6 Jan 1851, aged 83 (born ca 1768). Their children: Wm 1798, Peter 1806, Thos 1800, Sarah 1810, Mary 1813.
Best Wishes Douglas
ps I just bought FindMyPast. Have used it in the past. Way better than Ancestry.
