Moishe Campbell

Moishe Campbell was a family member on Mary's side who was active in 1937. Obviously Jewish based on his name, Bobby describes him as "one of the New York Campbells." As part of his attempts to locate Purgatory, Castiel steals Moishe's journal from Bobby's place. When Bobby realizes that his copy of Moishe's journal is missing, he tells Dean and Sam that he thinks Castiel stole the journal so that he could read Moishe's notes about H.P. Lovecraft, an author who was fascinated with the concept of doors to other dimensions. Luckily Bobby had photocopied the journal.^{6.21 Let It Bleed}
