Named in 1920 for Jacob Halm (1847-1926) by his son Karl, who co-owned a tract here. Caroline Avenue shares the name of Karl’s mother/Jacob’s wife, and this neighborhood’s portion of Sherbourne Drive was initially Halm Avenue (see that entry for Karl’s bio), so I have no doubt that these folks are the streets’ namesakes. Jacob Halm was reportedly born Johann Jakob Halm in the village of Plattenhardt, Germany – close to the present-day location of Stuttgart Airport. He later moved to the town of Göppingen, some 20 miles away, and married Caroline Abele there in 1876. Around 1900, the couple and their five surviving children (out of seven) immigrated to Seguin, TX, which had a large German population. Jacob worked there as a jeweler until retirement. Sadly, he and Caroline outlived two more of their kids, including Karl – the only Halm to leave Texas for Los Angeles.
