Uncle Harry and his wife Aunt Lily (or Lilly). Harry is one of Mama Lori's three brothers, at least two of whom (Donald and Harry) had orchestras in Harlem in the 1930s-40s, which I imagine were similar to the Teddy Wilson orchestra, but without the big recording contracts. Photo seems to be from the 1950s, by which time (I believe) Harry worked for the French Line (transatlantic ocean liners).
