Heilmann is a German language surname. It can be tracked to early 16th-century Protestant families in south-west Germany (various locations); In France, it has spread around 1545 to Mulhouse (MÃ¼lhausen in German), a city now in the Alsace region. Members of the Heilmann family of Mulhouse, of Protestant faith, issued from Lorentz Heilmann, a cooper, common ancestor born in 1545 in Niedernhall (now in Germany) and having established himself in Mulhouse :
Jean-Gaspard Heilmann (c. 1718 â€“ 1760), French painter
Nicolas Heilmann, Burgmeister (mayor) of Mulhouse from 1753 to 1766.
