We live in a neighborhood called Del Ray in Alexandria, Virginia. Our house was built sometime between 1923 and 1926. We wonder if it is a kit home because of its style (and because we're near Potomac Yard - an early railroad switching yard), but haven't come across a manufacturer/ floor plan yet that matches. Any ideas? Any guidance would be much appreciated! Thanks!
