Another technique you can try, since you want the first letter to be "P," is to start by constructing a list in alphabetical order...
Names starting with Pa...
Pe
Pi
Po
Pu
Py
Ps could give you Psyko! 🤣
If you get stuck, start adding the next letter...
Names that start with
Paa
Pab
Pac
Pad
Pae
Paf
Pag
etc.
