Dear Tara - my you guys are good! I have never see the will of Frederick Kapp or of Mary Kapp and I think the excerpt you pointed me at explains that (his will being unadministered by his wife until she died, her sister Isabel becoming the trustee. Subsequently Isabel's relative Edward Waugh, a businessman from Gateshead, England, became joint trustee.
I have the Indenture whereby the business left to them by their parents was divided between them in 1893, my grandfather selling his share to Charles Peterson.
My grandfather went on to become a doctor in Gateshead. I wonder if the trauma of his parents death influenced that decision. Certainly be became very close to Edward Waugh.
Thanks again for your help.
Marco
