|Old Hemlock is eligible for listing in the National Register of Historic Places under Criterion B: Literature, Recreation, and Art for its association with George Bird Evans4 as well as Criterion C: Architecture. Its period of significance is 1939-c.1975. It meets Criteria Consideration G: Properties that Have Achieved Significance Within the Past 50 Years for Evans' literary significance. Under Literature, Old Hemlock is significant as the home of Evans, one of the world's foremost authors on upland bird shooting and bird dogs. His work has a nationwide following, yet it is based almost entirely in the Allegheny Mountains of West Virginia and southwestern Pennsylvania. The period of significance under Literature begins in 1939, when Evans' association with the property began.5 Though he continued writing and publishing until his death in 1998, the period of significance ends c.1975, following the publication of his most widely known work, The Upland Shooting Life, and his following rise to prominence in the field. Old Hemlock is also significant under Recreation, as Evans was the first breeder of a line of English setters whose descendants are today treasured by bird dog enthusiasts throughout America. The period of significance for Recreation is 1947, when the first litter of Old Hemlock English setters was whelped at Old Hemlock. Evans was also a talented and locally significant illustrator and thus Old Hemlock is also eligible under Art. Evans painted and drew professionally for magazines from 1928 until 1947, with a brief stint as a naval illustrator during WWII. The period of significance under Art is 1939 to 1947. Finally, the original house at Old Hemlock is locally significant as an example how early settlement architecture was adapted to in 1939 to meet the needs of Evans and his wife. The period of significance under Architecture is 1939 when Evans made substantial changes. The house changed very little since that time.
