Only mention of a Buckborough I found was in the publication "The Pioneers Of Beverly" by Viola M. Collins.
In the Westover area is Elizabeth Buckborough wife of Jonathan (John) Shaver a United Empire Loyalist. They had 3 sons and 8 daughters and descendants are still on the property. Can find many Shavers buried in the Westover Baptist Cemetery, but no Buckborough's in any of the Beverly Cemeteries.
