http://vitals.rootsweb.com/ca/death/search.cgihttp://vitals.rootsweb.com/ca/death/search.cgi has one Glenna Rozier. She died in Sacramento in 1968. You could try for an obituary, if that is your Glenna. If it listed her survivors and her brothers were among them, you'd have her maiden name.
They have an Alfred Rozier, too; he died in 1973, in San Joaquin County.
If these are yours, at least you have a general area to look in - central California. The obits will usually tell you where the survivorsd were living at the time, which sometimes helps.
