23rd Fighter Squadron pilot help

[KM1957]

Would anyone have the names and serial numbers for these three Lieutenants (pilots)? They were assigned to the 23rd Fighter Squadron, 36th Fighter Group in late April of 1945. I have been unable to decipher the names/numbers from the unit records, both on microfilm and CD from Maxwell. I will list them with what I can somewhat deduce:

????? Brown, Jr. serial looks like 053?3??
Leo R. Pei??? serial looks like 0829629
Ros?? ? Wyman(?) serial is 0774400

On Brown, I cannot make out anything on his first name. On Pei?? I am not certain even the first few letters are correct. On Wyman, I am not certain of any of the first or last name, but put down what I can make out. Thank you.
