Match name in 1 column with another for a dynamic range

So I have this particular set of data in which Column A contains the full name of the kids, Column D contains the first name of the kid, Column E contains the amount they have been charged.

I want the name of the kid in column A to come in place of the numbers below them and in sync with the name in Column D, now I could just copy paste the entire range 1 row below, but there are kids of the same family and they have 2 names together example on row 18,19 so If I try to copy paste it will not fit perfectly...

I literally have no Idea how to go about it hence have no prepared code on it..

If you can solve this issue for me, you're god. Simple.
