Our thackeray line was the only line in HA in 1760's, first sign of a thackeray in HA is our Francis marrying mary Elmer. So yes the two johns who married mary's should be related in HA BUT Francis did not have two JOhn's!!!!
Maybe we have to recheck the John who married in Salton and somehow get a second proof he was son of fRANCIS.
As for wills, my folks are always SOO poor I doubt I could get so lucky ...........
Children of Francis T and Mary Elmer who married 1764 in HA

Jerimiah born 1776 married to Mary Hicks in 1798 living in Rillinton at the time, and buried in HA, his gravestone says Jeremiah T of Falsgrave died July 15 1858 age 80 yrs and Mary Thackeray wife of J. died March 27, 1850
2.
John T. married Mary Dawson and died 1878 in Butterwick York, born 1785
3. I have the will of my Joseph who died in Canada
BUT his wives are Mary Horsely b. 1767 HA, died May 5 1808 in Appleton. A second wife Mary that I know nothing about died May 25 1825 in Appleton.
maybe some of the others researchers have other T deaths.
