I looked at your other postings and found your mother's birthdate so considering her age I went to the Social Security Death Index and found this

MARY V HENRY-SAYLES 08 Sep 1927 10 Jun 2001 (V) 48098 (Troy, Oakland, MI) (none specified) 363-40-2149 Michigan

I tried to find an obituary online but have been unsuccessful so far but we might be able to find a volunteer to look into local papers ?????
