I got more information from my father who is 65 years old he remembers visiting the east coast and visiting an uncle Wilbur and Bruce who I guess were Olca's brothers. My father also remembered that Olca's father was a game warden who used to cruise th Potomac River looking for poachers. My father remembers that the grandfather lived into his 90's as did my great grandmother Olca. So it sounds like the Sigafose's have good genes for longevity.
