Where did the Lincolns live after the Globe Tavern?

[Steve]

If George Henry Helmle was the ultimate source that the Lincolns lived at Fourth Street (or Monroe) for a few months between living at the Globe and Jackson & Eighth (as indicated by the Burlingame citation), where did he get that information? George was born in 1853:

So, he couldn't have been an eyewitness. His family/parents aren't in the 1850 census in Springfield, but I did find George's parents', (William and Eliza Helmle), 20 Jan. 1851 marriage record from St. Louis, indicating they resided there at the time:

   

So George Helmle's information about the Lincolns' 1843-1844 home would have to come from another Springfield resident outside of his family.

Also, perhaps the William E. Barton papers should be checked for any correspondence relating to the Fourth Street address since Barton first published his book in 1925.
