I just found your message by doing a Google search and am beside myself with excitement as I have been researching this family for 3 years! John and Eliza Rae were my ggg grandparents. Eliza's maiden name was Scott, and Ellen/Hellen Park was her sister (nee Scott). If you are researching this family I have lots of information I would love to share, as well as further photos.
Theodore Rae has a particularly interesting story, which was the mystery which started me on my family history quest, and something I am still trying to solve.
Seeing the photographs you mentioned would be an absolute dream come true for me, and I will look forward to hearing from you.
Many thanks, and so excited to have made contact! Sophie
