Retired and have made genealogy my passion! Sarah K. Gill's parents were D W J Gill and Amanda Eskew/Askew. They wed 10 Oct 1880 in Bastrop but her surname misidentified as "Escur" per https://familysearch.org/
No clue of the meanings behind the initials for Mr. Gill. He's found with parents 1860 TX-Washington-Not Stated-Image 60 and 1870 Washington-Precinct 5-Image 18. Amanda's parents were Levi Eskew and Minerva Cox. They wed either 4 Jul 1861 or 29 Jun 1861 in Bastrop. Levi was born ca. 1835 in Alabama. Find him 1860 Bastrop. Find Amanda in her stepfather's, John Carter, 1880 Bastrop-Not Stated-011-Image 34 home. Does that help?
