Company Names, addresses, dates: ¹
  H.H. Denning, Glasgow near Wilson Avenue, Portsmouth VA (1890-ca.1892)
  H.H. Denning, 1332 County, Portsmouth VA (ca.1900)

Notes:
H. H. Denning first appears in Portsmouth City directories in 1890. He appears again in the 1892 directory, but is not listed in the 1897 directory. Then he shows up at a new address in the 1900 directory, but isn't in the 1902 or any subsequent directories. I don't have Portsmouth directories for any years in-between the years listed above.
(more information will be added when I get around to researching this druggist)
