Henry's death certificate is available online from the MO state archives.He died 26 February 1956 in Marionville, MO and is buried in the Odd Fellows cemetery there.The certificate says his parents's names were George Baxter and Mollie Collier.It confirms his birth date and place as the same as what you already have.Sadie survived him.
