Thomas Prosch, who named Conkling Place W after his mother, didn’t neglect to name something after himself. Prosch Avenue W runs about ¼ mile from W Barrett Street in the north to 13th Avenue W in the south. It appears as Prosch Place in Prosch’s Queen Anne Addition to the City of Seattle in 1909. Six years later, Prosch was killed in a car crash that also took the lives of his wife, Virginia; painter Harriet Foster Beecher; and Margaret Lenora Denny, namesake of Lenora Street.
