Final answer:
New Jersey allowed unmarried women property owners to vote in 1776, but by 1807, it restricted voting to free White males, ending early women suffrage rights.
Step-by-step explanation:
In the late 1700s, specifically 1776, New Jersey was the only state to extend the right to vote to unmarried women who owned property worth £50, leading to a significant step towards gender equality in suffrage. However, by 1807, the state revised its constitution, thus ending this progressive practice by restricting voting rights exclusively to free White males. This significant shift ended a period where New Jersey stood unique in allowing certain women the ability to participate in the voting process.
