Hi Colleen.
I am not searching this family, but I remember a query on this or similar surname earlier this year so did a search of the BB archives (Click on search at the top of the board and search for postings some back to 1998) and came up with the following information posted under Scalf,Scarff and orher variants:

Two books mentioned:
SCALF FAMILY HISTORY by Elmer D Scalf
CHRONICLES OF THE SCALF FAMILY by Henry Scalf

Website:
www.scalf-family.org

All these include SCARF/SCARFFE etc

Hope this helps
