Hanover is named after the German city of Hannover.HistoryIn 1727, John Digges, an Irish nobleman of Prince George's County, Maryland, obtained a grant of 10000acre of land where Hanover is now located from Charles Calvert, the fourth Lord Baltimore. The area was called Digges Choice, and in 1730, a group of Catholics started the settlement that became known as the Conewego Settlement. Settlers from both Maryland and Pennsylvania began moving into the area in the 1730s. At this time, the northern border of Maryland and the southern border of Pennsylvania did not agree with each other, and the area that is now Hanover was in the disputed area claimed by both states. This led to numerous disputes about property ownership from the 1730s until 1760. The dispute was settled when Maryland and Pennsylvania hired British experts Charles Mason and Jeremiah Dixon to survey what became known as the Mason–Dixon Line. This line was surveyed between 1763 and 1767, and put an end to decades of disputes over rights and ownership.
