Hi Nell I read your statement that the Wann family had married several times into the Williams family and the went to California. My Great Grandmother was Sarah Cathering WannShe married Robert Allison Williams and they went to Calif 1857. I do not have their marriage date but i believe it was close to the time when they went out west.He went earlier with brother Oliver and layed stakes on land.Then with his parents Phianea and Martha (Polly) (not sure of her last name I believe was Logan) Williams and many of their Phineas and MarthasChildren also being Robert and Olivers brothers and sisters went west.4 of the siblings must have stayed in Ark or Benton Co.Mo.Alexander being one. I do not have the other names. One Brother stayed with land and animals.He had a sick wife.They came back Well Robert did sold land later.Now you mentioned other intermarriage of Wann and Williams who were they?Could one of the Wanns have been another Sarah?
