Hi Andrea,
I've looked at the Eberhardt information and here are my comments.
1. The Johann Eberhard mentioned in the Viennese registration document dated April 1770 might not be the same person mentioned in
the parish records for Eberhardt #482 even though the church record's commentary indicates otherwise. They could also be relatives,
e.g. cousins or even brothers (see comment 5 below). There is also the matter of the various spellings of the surname.
2. The registration documents of 1770 only mention that Johann was a farmer and the head of a family of four (the names of the wife and
their two children are missing). The exact place of origin, not just Lothringen, and the ultimate destination of settlement are also missing.
3. The church records for Johann Eberhard #482 that you submitted do not mention this wife and these two children which is unusual. They do
indicate two wives. His first wife (NN - no name) bore him a son in 1766 that was named Johann after the father. That was customary.
The birth was registered in Tschanad which indicates that the family was already living in Tschanad. Since the mother of the first son is unknown
(=Sohn von unbekannter Mutter) and there are no church records in Tschanad, it is also possible that they came as a couple to Tschanad from
another village. Since there are no other siblings it is possible that she passed away during his birth or during the birth of another child, which
was common in those times. If there were other siblings they could have died as young children.
4. His second wedding in 1778 was to Anna Maria, with unknown surname (NN), and was more prolific with 3 children. One of these children
was also baptized with the name Johann. So he had two sons christened Johann from two separate wives.
5. One of the difficulties with our ancestors is that they used the same Christian name several times, e.g. with Eberhardt # 483
there are 2 Johanns and 2 Johann Peters and 2 Annas which confirms this naming habit. I've experienced the same problem within my family.
6. Suppose Johann Eberhardt/Eberhard/Eberhart came as a boy with his family to the Banat, as part of the small Swabian trek of 1744 - 1762.
The registration records in Vienna would not mention him by name; only the name of the father, the size of the family and the date of registry.
Researching these old records sometimes give us a better appreciation what our ancestors experienced, and how fortunate we are.
Regards,
George.
