Hi Opal,
Most of our data regarding birthcharts come from Lois M. Rodden's astro databank, a great deal of birth details are featured there that she picked up herself, however she was prone to rectify time when she wasn't sure.
Are the rectified charts marked to denote rectification? I was under the impression that they had to be stated to be so.
She originately came from Canada, moved to the USA and married, she wasn't an astrologer before she joined "The Church of Light" who trained her that Thomas H. Burgoyne was involved with.
I like church buildings. I don't like being there for services. I go for funerals, weddings, baptisms, tea, or work. I prefer not to work at them though, you observe too much bad behavior from the powers that control the strings.
I'm just getting started with politician's birthcharts that are correct or dubious regarding the time of birth mostly from the era of when Lois M. Rodden was in charge of Astro Databank that includes many of her personal charts she collected.
I'm finding many politicians that have a Sirius or Alnilam connection by either Paran or projected on to the angles.
The rating system used by Astro Data Bank is on link below, however if Rodden wasn't completely sure i think she would rectify charts to show powerful stars:-
