In the lintel of the house entrance, alongside the tanners' guild symbol and the year 1783, the letters G and K can be read, standing for Gabriel Köbele. The discrepancy between written records and the house inscription can be explained by the fact that the building's renovation lasted from 1783 to 1784.

The personal details match the entries in the Alpirsbach church registers, which senior teacher Georg Albrecht (1881-1964) evaluated in an exemplary manner.

Let us begin with the butcher Sigmund Leibiger (born 1713). In 1746, he married Maria Margareta, a daughter of the tailors' guild master Johann Friedrich Wörner. Their marriage produced ten children, of whom the sons Georg Jakob settled in Frankfurt, while Gottlieb Heinrich settled in Brabant.

The Leibiger family were attracted by the silver and cobalt mining industry in Wittich and Reinerzau, which had flourished since the beginning of the 18th century, drawing on the depleted mines in Saxony (Ore Mountains) and Thuringia (Harz Mountains). As recognized experts, they found suitable employment. The Leibiger family is the most famous example of this.

Sigmund's father was Konrad Leibiger (1695-1744), a mine foreman at the "Güte Gottes" mine in Wittichen; his mother was the daughter of the carpenter Friedrich Maser. "He was only 21 years old when he married, born in Neuenstadt, now Neustädtel, near Schneeberg, where his father, Alexander Leibiger, was a citizen, and later in Eckershausen, Principality of Eisenach. Neustädtel and Schneeberg are towns that grew entirely from mining and have now merged. The main mines there yielded cobalt and silver, just like Alpirsbach, Reinerzau, and Wittichen. They are located very close to Aue, the now famous or infamous uranium ore mining area." (Georg Albrecht). Of Konrad's twelve children, most died young; only Sigmund and Karl Friedrich (a baker) were able to start families.

Christoph Friedrich Leibiger (1749-1794), Sigmund's eldest son, had become a saddler and established a saddlery workshop in accordance with his profession. He must have had enough customers for his products, as there were still plenty of horses and cows in Alpirsbach and its (monastery) administrative districts at that time.

With his wife Elisabeth Barbara, a daughter of the gatekeeper Johann Christoph Schneider, he had six children. The office of monastery gatekeeper is documented from the second half of the 16th century. In 1619, "Gatekeeper" Hans Schwenk, who had been employed at the monastery for over 40 years, died. His duties beyond opening and closing the two gates (the upper one between the main office and the brewery, the lower one by the former hospital) are unknown. He was a son of the monastery cooper Johann Friedrich Schneider (1722-1765).

His father, Johann Schneider (1684-1771), had already been a monastery cooper. As a reminder: the grape must harvested in the Breisgau region was processed in Alpirsbach. What remained after the wine paid to officials and priests was sold.

The Köbele/Köbelin family has been documented in Alpirsbach since 1701. At that time, the tanner Gabriel Köbele (1666-1735) married the baker's daughter Sabina Barbara Hetzel, who died later that same year at the age of 22.

From his second marriage to Jakobina Mick, presumably born in Nordweil/Breisgau, came, among others, a son, Matthias Köbele, who worked as a tanner, was also a foreman at the Eberhard and Unverhofft Glück mines, and later served as a messenger. Born in 1707, he married Sophia Elisabeth in 1735, a daughter of Daniel Zobel, the Fürstenberg mining master from Wittichen.

Matthias K.'s brother was Georg Jakob Köbele (1717-1777), also a tanner and a member of the local council. His son Gabriel Köbele was born in 1758 to Agnes Margareta Stortz (1721-1789), the daughter of a stocking weaver. Gabriel died unmarried in 1784 and thus did not live to see the renovations completed. His brother Andreas then took over the property (see below).

The neighbors of the two Köbeles were Hannß Jerg Faßnacht, Andreas Köbele, and Ludwig Weitbrecht. Johann Georg Faßnacht (1749-1789) was a tanner. His father came from Reutlingen. He himself had twelve children with Christina Maria Adrion (1753-1818), the daughter of a blacksmith from Alpirsbach. Most of them found work elsewhere, such as his sons Johann Christian and Gottlieb in Switzerland.
