RE: Jackie and Lee & the Edies
If I recall correctly, both Edies were more or less left to their own devices by the Bouviers (including their sons/brothers). Phelan Beale did provide support after they separated but I’m nearly sure that ended once he got his “fake Mexican divorce”. Big Edie did have a trust fund from her father, but it was very small (he reduced it after he felt Big Edie embarrassed herself, the family, and her son at the latter’s wedding), realizing only a couple of hundred a month.
Oddly, the Edies did manage to keep up the place -more or less- and were still social in EH until a robbery in the late 60’s after which they became recluses. This was when the house feel apart, they fell behind in taxes, and retreated to living in 3 of the house’s 28 rooms.
When the place was raided and it made the news because of who they were, where they lived, and who they were related to, the whole family was mortified. The Beale brothers paid the fines and back taxes, while Jackie and Lee paid to repair the roof, plumbing, electrical, as well as paying to cart off tons of refuse. While a shell of its former glory, it was up to code and habitable.
Lee was trying to make a documentary about her and Jackie’s childhood in East Hampton (ie; monetizing their relationship) with the Maysles brothers, and the Edies were the only Bouviers left in town from those days, so she brought them over to interview them. The Maysles saw the potential, dropped Lee and her idea, and we were all gifted with “Grey Gardens”. IIRC, Lee did confiscate all the footage already filmed once they dropped her. I seem to remember, though I may be wrong, that the Edies agreed to do the documentary because the Beale boys were really pressuring mother and sister to sell the house, and they thought the money from the documentary would set them straight and save the place.
When Little Edie eventually sold the place, (to Sally Quinn and Ben Bradlee), in ‘79 she did write into the contract they could not tear down the house. Little Edie got something like $250K for the place then; when Sally sold in 2017, she got $16M.
