Hello Kathie,
Welcome to the thread. Both families, the Eberts and the Kramers are mentioned in Gerald Newton's booklet. Gerald Newton collected all entries of German pork butchers in the 19th century Sheffield directories. The entries on the Eberts are as follows:
Ebert, Michael, pork butcher, Change-alley. 1817
Ebert, Michael, pork, bacon and ham dealer, wholesale and retail, 15 Change alley. 1825
Ebert, Frederick, pork, bacon and ham dealer, wholesale and retail, 1 Pinstone street. 1825
Ebert, William, pork butcher, 73 Broomhall road. 1863, 1864
Ebert, Mr Charles, Crooksmoor side. 1864
Ebert, Mrs Frances, 14 Gell street. 1849,1864
Ebert, Charles, professor of languages, 3 Hartshead; h Steel Bank. 1864
It seems that the Eberts came from Künzelsau in Hohenlohe, North-Eastern Baden Württemberg, Germany.
In the official description of the Künzelsau district, the chronicler confirms in 1883: “There is specifically a considerable migration to England. At first it was Johann Michael Ebert, born in 1771, then Christian Friedrich Ebert, born in 1775, who went as pork butchers to England. Both were able to get into good conditions. After that they were followed by many young men who made their fortune there and were fond of returning in later years”.
This quote was translated from: Beschreibung des Oberamts Künzelsau. Hrsg. v.d. K. statistisch-topographischen Bureau. Stuttgart: W. Kohlhammer, 1883. XI, 911 Seiten. (Reprint: Magstadt: Horst Bissinger, 1969).
In Gerald Newton's Sheffield list there are 19 entries on the Kramers. If you wished I could send you them by e-mail. For that you've got to do two more posts for enabling me to send a personal message.
I suppose that the Kramer (originally Krämer) family also came from Künzelsau or not far away from there.
As soon as we have some personal contact I will send you the address of Künzelsau's town archivist, who can probably find out more on the Eberts and their forefathers in Künzelsau.
I personally would be interested in photos of the butcher shops or in letter heads of the butcher's firms. Perhaps you have got such material saved in your family.
Kind regards
