Yes, I had a question mark beside that date for William Materly's death -- I found what looks like him, "Anjaline" and possibly her younger brother Alvertis listed in the 1850 census.I didn't have Lucy listed among his sibs -- do you know her dates? And I have a brother Jefferson Matherly listed.OTherwise my list and dates match yours:)
Henry Burr Matherly married Malvinia Miller -- I have no info on her at all and sure am looking.They had at least 9 kids, including my great great grandmother Martha Matherly, also called "Mattie", born 1835. Mattie married Lewis Vermillion in 1869 and they had three children, including my great grandmother Ella (b. 1875/6).
All this seems to have happened in Indiana (where Lewis was born) -- and Ella spent her life in Terre Haute IN. I was born there too, tho have lived in Australia for over half my life -- so my searching is done by Internet.
