The census records for John Stewart and Abigail Burleson, my gggg-grandparents, are shown below. John and Abigail had many children, Sarah's older sister Cassandra "Cassy" Stewart married Nathaniel Wyley Cude, Sr. in Gonzales County, Texas. Her younger sister married the same Nathaniel Wyley Cude, Sr. after Cassandra's death. These are the census records that show them living near one another:
1850 Bastrop County, Texas, John Stewart is on line 25
1860 Gonzales County, Texas, John Stewart is on line 36. Nathaniel Wyley Cude is on line 14, but his last name is shown as Winters.
1870 Gonzales County, Texas, John Stewart is on line 19, Nathaniel is on line 5 with Cassandra Stewart Cude.
1880 John is on line 10. I don't have a record for Nathaniel and Cassandra or Sarah. Most likely moving to Frio County, Texas at that time.
1900 Nathaniel is on line 47 for Frio County, Texas. Both Cassandra and Sarah had already passed away.
Good luck. I hope this helps.
