You might have heard it from me. I read about it in a book called
Vindicating the Founders by Thomas G. West. There's a chapter on property requirements for voting, with a chart of suffrage requirements in the state constitutions, in the revolutionary/founding era. Some states had property requirements, some awarded suffrage to those who paid taxes, some had neither.
New Jersey was actually the world capitol of female suffrage, if I remember right, but I believe West found female and black voters in other states. Like I said, the women who voted were usually those who had property, but had no husband/father/brother, or other male to manage their affairs.
Due to femme covert, women's property was considered to be their . Never mind. I was going to explain it, but I'd probably botch it. Here's a link.
