[1] From around 1846, he lived in Transylvania, appearing in the artistic circle of Theodor Glatz, who recommends him locally as a talented painter.

He taught painting in Hermannstadt (today Sibiu), at the Brukenthal Art Gallery, where in 1847 he met, as a student, his future wife, Clara Adelheid Soterius von Sachsenheim.

Her portrait, painted in that year, is considered representative for the Biedermeier period in Transylvania, expressing on a bucolic background, the personality of the model, the cromatics and the discreet elegancy of the dress.

But despite resistance from the family, who had doubts about giving consent to marriage due to Theodor's insecure position and also because of his religious and status differences, the couple were married on 12 August 1847 in Mehadia.

[4] In the context of the 1848 Revolution in the Austrian Empire, an open letter written by his sister Sophie von Scherer to the 1848 Catholic bishop conference at Würzburg, requesting ecclesiastical reforms, such as the abolition of the celibate and worship in the German language, would cause public controversy.

He also painted: In the Benignis folk calendar of 1853 we find an advertisement for ‘Theodor Sockl as academic portrait and historical painter in the Fleischergasse no.110.’ But the economic and social environment left by the 1848/49 Revolutions in Europe made it difficult for Theodor to earn a living, so he was forced into an unsettled wandering lifestyle in order to find work.

To cover the funeral costs, Theodor’s brother, Moritz, sold the paintings that were left, including hundreds of studies, to a Viennese junk dealer.

Carl married his cousin Emma, daughter of Theodor's brother Hermann, they had six children, five survived infancy and all lived and died in England.
