PEASE please!

In the course of looking at the PEASE men that served in WW1 it all gets a bit confusing. Perhaps you have a snippet of info that might help?

There is a William George T Pease, son of George, born on 25 August 1885 (assuming I have the correct WW1 record matched to the correct man). Can anyone confirm this birthdate, and does anyone know what the T stands for?

There is also a William son of James, also born in 1885. Does anyone have an exact birthdate for him?
