Hope that you have not stopped looking for persons with the surname CLENDINEN. Just today when reviewing xeroxed pages (made in 1994) of LIGHTBOURN'S ANNUAL and COMMERCIAL DIRECTORY of the Virgin Islands of the United States (1900 & 1918), there I found the names with listed businesses of 3 persons with variations of the CLENDINEN surname.
Published in 1900 were: W. Clindinen - Hardware
J.A. Clindenin - Goldsmith
Published in 1918 was: C.E. Clendinen - Tavern Keeper
Notice different spellings of surname.
Hope that this is helpful information.
