Glad that I could be of help. I have more information if you are interested, including two young daughters of Erasmus, Sr. that died young. Also Erasmus' siblings and half-siblings. I am descended from his half-brother, Andrew. I would be interested in seeing the pictures of the homes if that is at all possible. I guess Uhler's Alley was named after Erasmus, although I have seen it mentioned as Uhler's Run on 17 Nov 1753, which was long before his time in Balto. Uhler's Run is even on a map of Balto. in 1732.
I have a 45 page Uhler family tree. There is one person that I can't place on the tree with any proof, although I am sure he goes on there somewhere. Maybe your grandfather has him on his family tree. He is Philip Uhler (c.1768 - 11 Dec 1855). Philip married Mary (Botner) Uhler (c.1770 - c.27 Nov 1837) on 10/20 June 1793 at Zion Lutheran Church or the First Reformed Church of Baltimore by license. All but three of Philip and Mary’s children died in childhood or youth. Philip came to Baltimore City, MD from York County, PA. He was a saddler by trade, but became a commission merchant and grocer. In 1796, he had a saddle and harness-making shop at 11 Cheapside, and Erasmus Uhler had a currier shop at the same address. In 1796, Philip lived at 7 Bank Street. In 1799, Philip was a saddler on 9 Cheapside wharf in Baltimore, MD, and no home address is given. Philip was with the American troops which met the British at North Point, but not with the advance column which engaged in the battle.
I have more on Philip too. Also, his grandson was Philip Reese Uhler(3 June 1835 - 21 Oct 1913). Here is a bit of his biography - Philip became an assistant librarian in the Peabody Library from about 1861-64. In 1864, Philip was the first person to collect insect specimens and place them in a museum. He then became an entomologist at Harvard College, but eventually returned to Baltimore. From 1876-80, Philip was on the staff of Johns Hopkins University as a Professor of Natural History. Important parts or all of Philip’s collection of Heteroptera are housed on the fifth floor, East Wing, of the National Museum of Natural History in Washington, DC.
I have a picture of Philip Reese Uhler and his son, Horace Scudder Uhler (5 Aug 1872 - post 1952). Horace was Professor Emeritus of Physics at Yale University in 1946. He wrote many papers on Mersenne Numbers and other mathematical subjects. I have a book by Philip Reese Uhler and a Johns Hopkins alumni medallion of Horace's that I got on eBay.
If you would like to email me privately, that will be fine.
