Kathy,
None of my records match to that area. I don't have any info. on Frederick William. Elizabeth (not listed with your maiden name) Melcher (not sure if it's your ancestor) I have 2 records:
Death March 4, 1925 Kenton County, KY volume 15 certificate 7107 - Directory of births & deaths, series 3 Volume VII MAD-OWS board of health of KY 1921-1925.
Will dated March 2, 1939. List of Jefferson County, KY wills in possession.
Good luck.
Linda
