I am interested and will contribute as time allows. On the Fourth of July 1906 my maternal great-grandparents and their children relocated from South Dakota to Snohomish County, Washington.
I am distantly related to the 12 Hickok siblings from Bellingham, Whatcom Co., Washington who made newspapers all across the country simply because all their first names began with the letter "Z" (Zelum, Zatha, Zella, Zarnell Zalmond, Zorna, Zorin, Zelpha, Zerril, Zale, Zelbert, Zoland, and Zane (

Undoubtedly my favorite Washington relative is Roger Sherman Greene (

He was the minister at the wedding of each of his four children. Probably what he is remembered most for is his single-handed attempt to stop the lynching of two individuals who had been broken out of jail by a mob.
