It is an interesting circumstance that the part of the custom 
house which was built in 1876 was purchased by Colonel Frank 
N. Wicker, who had, for eleven years, occupied it as collector of 
customs. He moved it to a lot on Duval street between Front 
and Greene streets, three doors from the Jefferson hotel, and 
occupied it as a real estate office. It is now owned by the Key 
West Investment Company and the lower floor is used for an 
office by them. After this building was sold, and until the comple- 
tion of the new building, the custom house business was carried 
on in a building on Whitehead street, between. Caroline and 
Eaton street, which was erected by Mr. Benjamin Sawyer, 
and long owned and occupied by Mr. E. L. Ware. It was after- 
Wards torn down, and on the site Mr. W. L. Delaney erected 
his present residence.
