Vicki Berg said her mother discovered the letter, addressed to W.J. Chafee at the Purina company and his wife Margaret Ann, and some accompanying photos when she moved into her Westminster home in 1960 and she asked Vicki to find their rightful owner about a year before her death, KMGH-TV, Denver, reported Wednesday.
"They've looked at me for years and I didn't know where they were supposed to go," Berg said.
Berg said she and a friend enlisted the help of KMGH-TV producer Marianne Mckiernan when they were unable to locate the family on their own.
"Once you get a name, you might get a sibling's name, a spouse's name, a child's name, and the more names you get, the easier it is to keep drilling for information," Mckiernan said.
Mckiernan was eventually able to track down descendant Carolyn Chafee Howard and Berg presented Howard and her family with the letter.
"I just am tickled that you sent this because you took the time. Most people just say, look, it's one more thing on my to-do list," Carolyn Chafee Howard told Berg.
