The University Library Lund in Sweden keeps the most extensive source for horn music from the first half of the 18th century. The music is a handwritten collection of the Academic chapel. Many of the composers therein had somehow connections to the court in Dresden. It is possible that the copier was a hornist who visited Dresden.
This collection Wenster contains 18 concertos for horn - and not 17 how it is always said.

No. 15 Johann George Roellig (1710 - 1790)
Concerto ex D major for corno concertato, 2 violins, viola and basso
Only the name Roellig is recorded in the manuscript. In the RISM, Johann Georg Roellig is noted as a composer. Since the composer is to be found in the Dresden area or in connection with the Dresden court, it could be Johann Georg Roellig. He was born in Berggiesshübel in 1710, attended the Kreuzschule in Dresden and received lessons from Zelenka and Reinhold at the expense and support of Count Brühl. He studied theology in Leipzig and was heard there by Prince Johann August von Anhalt-Zerbst on the organ and cello. The prince took Roellig with him to Zerbst, where he became a court organist and chamber musician. He later became deputy bandmaster and, after Fasch's death in 1758, actual bandmaster in Zerbst.
However, there is also another composer who may be considered:
Christian August Roellig was born in Königsbrück near Dresden and was court cantor at the court chapel in Dresden from 1730, as was mentioned in 1741.
