Cullison FamilyTreeDNA Project Website- Background
Callison, Collison, Cullison
The Cullison families of Baltimore and St. Mary's Counties have been thoroughly researched using traditional genealogical source materials by Norma L. Cullison Myers and other family members. The results were published in two volumes in 2000:CULLISON DESCENDANTS FROM MARYLAND WESTWARD: BALTIMORE COUNTY ROOTS and CULLISON DESCENDANTS FROM MARYLAND WESTWARD: ST. MARY'S COUNTY ROOTS.
Unfortunately, no proof has ever been found as to whether or not the Cullisons of Baltimore Co. and those of St. Mary's County are related. Nor were we able to determine from where the Cullisons originated besides the general U.K.
