No, this is not enough. You should provide evidence that it is really used as a name.
Databases contain errors of all kind: Spelling errors, wrong gender marks, confusion of given names and surnames, confusion of titles and given names, confusion of abbreviations and given names, to name a few. Compilations from different databases tend to amplify these errors. So databases have to be used with care.
EDIT: Specific care has to be taken about US census data: Traditional censuses were taken by people writing down name they understood (listening comprehension and spelling error are possible) by hand and the names have to be transcribed from handwriting (more errors possible). A name only attested in US census data and nowhere else is probably an error.
