I've assumed for a long time that the Spencer Adams who was a Texas Ranger was from the line of William's son Spencer. Have you found any information on this.There is one posting on the internet and I've found another episode, in years past,referring to Ranger Spencer Adams.I will locate it and pass it on to you.
William Adams was a Constable in Kentuckyaround the time of his death. Spencer (1759) was a Constable in a Colonial Court. Spencer(1759), later, was a judge in Kentucky.
My father was also Spencer J. Adams, Great-grandson of Jesse Adams who was William's half-brother.His grand father's name was Spencer and they lived in Searcy County, Arkansas from the early 1830's.
