Q. If one refers to the DeVos (pronounced DeVOSS) family members in the plural, would they be the DeVoses or the DeVosses? If the former, that would appear to be pronounced “DeVOSEes” rather than “DeVOSSES,” as would be correct.
A. “DeVosses” is the plural for the DeVoss family, so you must use “DeVoses.” We aren’t allowed to misspell a name in anticipation of its mispronunciation.
