Brewery St is still there, running off New Town Row, though none of the original buildings remain. Below is a map from c1889, though it was very similar in 1911. It shows numbering. the black numbers are certain. the red there is some doubt, depending on whether the building marked 29 is listed in Brewery st or New Town Row. Certainly 21 is either the one so-marked, or the one next to it on the corner. The 1912 Kellys (which would refer to 1911 ) lists George at 21 as a beer retailer, meaning almost certainly that he only had a beerhouse licence and could not sell spirits or wine. He is also listed there in the 1910 Kellys, which would refer to 1909, but not in the 1908 edition (referring to 1907, or the 1913 edition (referring to 1912), so it looks like he was there for about three years. The electoral roll for 1912 lists him as living at 8 Belgrave avenue, which was a double terrace of houses off Belgrave Road..
In the 1903-1908 editions of Kellys (referring to 1902-1907) he is a shopkeeper at 69 Eversley Road, Smallheath
Miss-spellings in Kellys can be a problem. In the 1913 edition it does not list an Ameghino, but does list someone as George Arnechino in the streets section and as George Amechino in the names section, both at The Ivy Green pub , 16 Clement St & 22 Edward St. this seems to be a long thin pub with entrances in both streets. The spelling is corrected in th e1915 edition. By 1921 he is at the Hay Mill Tavern , Coventry road, Haymills.
