My wife only had six ancestors in the SSDI:
1) Wilbur Johnson (1912-1991)--death place listed as "HC"
2) Grace Johnson (nee Mortier), 1913-2000
3) Ola Lake (1906-1969)
4) Anna Lake (nee Apgar), 1913-1987
5) Henry Mortier, 1885-1966
6) Caroline Mortier (nee Freund), 1884-1981--spelled "Coroline" in SSDI.
Her parents are living as well.
