Then there's the Catholic marriage record of Ferdinand's son:
When researching church records written by Germans it's common to find the + symbol to indicate that an individual had died (gestorben). You'll typically see such a notation in marriage records when a widow/widower remarried (referencing their previous spouse) or a parent died before their child married. So, I believe the record translates to "Joseph Ebert, son of Ferdinand Ebert, deceased for seven years, and Agatha Albrand."
This transcription from an 1862 church marriage record is nothing out of the ordinary, except for the number seven, which is written in superscript, that is, to the right and slightly above the cross. This notation may be normal elsewhere, but a couple of St. Louis County librarians -- one very familiar with local Catholic records -- and someone at the St. Louis Archdiocesan Archives had not seen a record like this before.
This notation is very important to the research of Ferdinand EBERT. That the math is a little off (1862-7=1855) doesn't really concern me. What's important is that this bolsters the City death register, in which the name was indexed as EBUT -- understandable when seen on microfilm.
