Speaking of transcribers who cannot read the old-fashioned cursive, how's this for a series of errors? From a death certificate, as indexed on FamilySearch, (searching for Mary Ann V. Caylor, who married John Edmondson Headrick):
Death Record of Pollyan Fredrik (should be Hedrick), whose mother's name was interpreted as "Matilda Doren" (instead of "Dover). Her father was correctly transcribed, but scribbled and misspelled (due to a nearly illiterate coroner), as "Gore Caylor" (instead of George Caylor). This is in the death record of Mary Ann V. (Caylor) Headrick, who is indexed as "Pollyan Fredrik."

I found this by a complete fluke, using wildcard searches in a search for another family member. Needless to say, I was thrilled to find a record of these elusive individuals!
