I am researching Julia Ann Taylor's parents also. I am a gggranddaughter of John Phillips. I have been looking into Zachary Taylor's descendants because when Oregon was 100 years old my mother wore one of the former first lady's dresses. This was in 1959. I was 7 years old at the time and remember my mother could barely move in the dress or the threads would break because the dress was made out of silk. The dress made the journey from back east somewhere around Cape Horn. Anyone on my mother's side, including my mother, have passed on so I have to do my own researching. I understand someone in Oregon has kept our family tree but I don't know who it is. I suspect one of John Phillips descendants in Sublimity, Oregon would know who has the tree. Good luck in your search.
