My Gr Gr Gr Grandmother, Mary Ann Alexander, died in 1877 at the Mayfield Hospital, in Mayfield, Mi. Just outside of Lapeer MI. We have been unable to find where she was buried. Have checked some local cemetaries, but no luck. We have death record from Lapeer County, but no mention of place of burial. Also searched in the Mayfield Cemetary right next door to the old hospital and found no markers. Does an index or listing exist somewhere that may show a burial with possibly no marker having been placed. We wish to find her grave and place a proper marker or stone. Any help is appreciated.
