Have just come across this thread while trying to discover more of my great grandmother Barnett's family in Lin cs., including Pattern, Booth, Ingram, Twiddy, Mayne, Reader. My great grandfather worked for Charles Dolby of Spalding from 1860 to 1864 and let to him what was then a smallholding called The Manor House. Charles Dolby 1792- 1868 was an auctioneer and land agent; father was Thomas Dalby, mother was Mary, dtr of Henry Booth and Mary; wife was Ann Markillie, who appears to have hailed from London.
Henry Booth was also father of Susanna and grandfather of Henry Booth Barnett and grt grandfather of Ann who married my grt grandfather William Hollinshed Brady.
Could well be related through Thomas Dalby.
