Hi Since there are several family lines with the same surname that are not connected these people may not be related.'Burton' is not in my line so I have not done any research on the family.
George B. Burton, born 09/20/1846, married Sarah Nancy Harrison on 04/26/1866.Sarah, born 02/26/1849, is the daughter of Matilda Davis and William Henry Harrison [grandson of Zebulon Harrison and Margaret Cravens].
George and Sarah had children:
Ada Lee Burton, born 03/04/1867[Ada is the source of the pages from the Bible.]She married a Hunker.
George N. Burton born 11/11/1871
Francis H. Burton born 05/01/1874
Matilda Davis Harrison also remarried to a Burton, but his name is not recorded on the copy on my copy of the pages from a Harrison Bible.William H. Harrison died in 1857 and when his estate was settled in 1862 'Matilda Burton' is listed as his widow.
