From the experts:
Maxwell may be thought of as one of the classic Baby-Names">Scottish names for boys, but two celebrities have recently used Maxwell for their daughters - Jessica Simpson bestowed it upon her daughter, Maxwell Drew, in 2012, followed by Lindsay Sloane's daughter, also born in 2012, named Maxwell Lue. Sixty-six parents chose Maxwell for their little girls in 2017, but that's compared with over 3000 baby boys named Maxwell, so while this name is used for babies of both genders, it's not truly a unisex name.
