William Hargrove in 1818 published a map of Micklegate Ward, the area in York where John Snow was born and spent his early years. Two landmarks along the River Ouse are shown in orange (The Guild Hall) and yellow (Ouse Bridge). The All Saints North Street church is shown in green (#1) and Snow birth-home is presented in red (#2).  In 1823 when John Snow was 10, his family moved to Wellington Row (#3).  Two years later in 1825, the family again moved, but this time to Queen Street (#4) where Snow's father accumulated land and rental properties.  Dodsworth School, where John Snow likely received his early education education from age 6 through 14 (i.e., 1819-1827) was in Bishop Hill (#5).
