Robert Daniels wed Jane "Green", 28 Nov 1889 in Williamson County. That's supported by death certificate for Isabelle Johnson viewable/printable on the same website. The 1889-date indicated on 1910 census where the couple enumerated as married for 21 years. While on familysearch, lookup death certificate for Susie Daniels (3 Jul 1903 - 22 Oct 1918). I'm not related!
