I don't hate them, some of them sound nice but it is a different way to get a new name. The others, although may have been 'childrens names' at some point are derived from other traditional names like how Sandra is from Alexander and Nancy came from Ann, but are distinct names in their own right.
Names that are 'made up' or are just repurposed surnames, misspellings or mismatches don't usually have the links that make them seem like 'proper' names.
And they might become thought of as more standard names as the bearers grow up but there are really not many children called Braylee in this country and there are so so many new made up variations with similar sounds. Like Rylee, Kaylee, Brynlee, Brinlee, Brylee, Caylee, Kalilee, Lylee, Kylee, Preslee, Kinslee, Kaislee, Marlee, Rynlee, Mckinlee.
All of which can be spelled with a 'leigh' or a 'ly' or a 'ley' ending.
There are just so many similar names that the 'individuality' of them is lost and they become one big slew of similar american sounding names.
With more traditional names, there wont be many alternative names that fully rhyme and sound similar.
