Notes

^ Sources differ regarding the construction date of the Isam White House. Harrison et al. give a date of 1906 in their inventory of the Alphabet Historic District,^[2] evidently based on the City of Portland's contemporary public records database.^[3] In National Register documentation focused specifically on the Isam White House, Faulkner and Sekora base their 1903–1904 date on primary sources.^[4]^: 3
