A plaque at 426 Henry St. gives her year of birth as 1850, not 1854. However, on 9 January 1854, the Jeromes lived nearby at number 8 Amity Street (since renumbered as 197). It is believed that the Jeromes were temporarily staying at the Henry Street address, which was owned by Leonard's brother Addison, and that Jennie was born there during a snowstorm.[7]
