My wife¹s grandmother¹s sister Catherine ³Kate² (MacKenzie) GORDON (b. 1878, PEI) lived in Boston from 1903 to her death in December 1958. Her husband Oliver Purl Gordon (known as Purl¹) died in March 1948. ³Kate supported parts of her extended family by keeping a rooming house at 91 Waltham Street in downtown Boston; had row houses (side by each), with 6 or 8 rooms that she managed.² This information is part of an old family letter that I found recently. Can anyone suggest how I could investigate this residence? Are there directories? Does the house still exist?
