John Bevan (1817 - 18xx) was an English American civil engineer and surveyor. Bevan was born in England. It is unclear when Bevan arrived in the United States, but by as early as 1851 he was working as a surveyor and civil engineer in New York and New Jersey creating maps of towns. According to the 1870 U.S. census, he was living in New York and was an American citizen. Very little detail is known about Bevan's life and work. From census data we can deduce that he was married at least one, but most likely twice based on the age of his eleven children. Gertrude, likely his second wife, was thirteen years his junior.
