Earliest Known Ancestors: married Mary Clay at Granby, Notts in 1768. Their daughter Mary (bapt. 1776, Granby) married in 1804 at Burton Joyce cum Bulcote, Notts. Descent is via Ann Tustin (baptised 1805 Granby Notts., m. George Gibbons 1829, Basford, Notts). See Hewitt pedigree for more.
Can't find William or Mary on the 1841 census for Notts. I have looked in the Granby PRs for burials from 1841 back to 1813, and at baptisms and burials from 1812 back to 1769. I found burials for John and Mary Gretton, but not for William and Mary Tustin. I looked for William Tustin's baptism in Burton Joyce from 1790 back to 1773 and found no Tustin events at all.
