Police say Lucy Johnson was last seen by a neighbour in September 1961 in the 10300 block of 145A Street.
During the initial police investigation, her husband at the time, Marvin Johnson, was considered a suspect. Police excavated his yard looking for clues into her disappearance.
Marvin Johnson died in the late 1990s.
In June, Johnson's disappearance was highlighted by Surrey RCMP as a cold case as a part of their 'Missing of the month series'.
Her daughter, Linda, also put out ads in a newspaper in northern B.C., because her mother was originally from Alaska.
Shortly afterward, she discovered her mother, now 77 years old, has been living in the Yukon and has another family.
"The original daughter of Lucy Johnson who went above and beyond to promote and try to generate tips all over B.C., actually somehow connected with a stepsister who she did not know she had at the time," said Cpl. Bert Paquet, spokesman for Surrey RCMP.
"The stars aligned, the timing was perfect."
Paquet says the experience has been emotional for both families, who have asked for privacy during this time.
