Arthur Fowlke

He was the child of Louisa Fowlke.  His mother married William Marrott after arriving in Utah, and Arthur was adopted by William.  His name appears as Arthur Fowlke Marrott on FamilyTree, but he would have been "Arthur Fowlke" in 1861 when he made the journey to Utah. 

The family sailed to America in 1861 on the ship Underwriter, and his name is listed as "Arthur Foulkes" on the ship manifest.
