Bill, So to put it succinctly William Haites(Yeates etc) marries Lydia Dickens in 1806 at Ampthill. They have a daughter Elizabeth Yates in 1807. ( In 1841 they are listed as Yales.) Elizabeth marries Thomas Bunker c1827 and the couple have 3 children Sarah c1831, William c1833 and Ruth c1835. Thomas looks to have died between 1835 and 1844. In 1845, Elizabeth marries for a second time to John Chapman. I presume you have found them in 1851 and any children. Also in 1851, William Bunker c1833 and Ruth Bunker c1835 are living with their grandparents William Yates and Lydia. It looks like Joseph is born between Elizabeth's first and second marriage. You don't give his surname. But you have certificates that don't show a father and you must have him in later census records. You could try bastardy bonds at A2A. There is no obvious Lydia Dickens on IGI. All I can suggest here is to use the Hugh Wallis site of IGI batches. http://freepages.genealogy.rootsweb.ancestry.com/~hughwallis/IGIBatchNumbers/CountyBedford.htm#PageTitle In batch, you can search batches in surrounding parishes using only given name of Lydia.
