"Jane Porter Robertson and Charlotte Porter’s father, James H Porter, came to Leadville in 1877 and to Breckenridge in 1883. Ralph’s father, Nicholas Noyes Robertson, came to Leadville in 1879 ~ Both James and Nicholas were miners. Ralph and Jane met at Colorado College and married in 1907. Charlotte, (“Lottie”) interred Lars at a suitable distance so it would not be assumed they had been more than friends. Helen Rich and Belle Turnbull were Jane and Lottie’s close friends and neighbors."
