Dominick,
I believe Great Eastern was located in New York (Long Island?), but they had a number of branch offices (similar to the way Terra Nova had lots of offices, such as Polar Trading, MB Trading, The Executioner, etc, back in the late 1999's or 2000). You likely had an account through one of their branches. I believe, for example, that Maverick Trading (out of Salt Lake City, later renamed TouchTrade) once operated through Great Eastern. In addition, another firm, located near Seattle, Washington (although I forget their name), traded through Great Eastern. Not sure of the others.
