Hi Bennet,
Your looking for schools near to your friends house 500 Southport Rd Bootle.
There's one school no one mentioned which is about 500yds away from your friends house.
Which is St Monica's R.C. Aintree Rd which was boys only.
Also St Monica's Fernhill Rd, for infants, and junior girls,which was opposite St Monica's church. The junior boys and girls met 4yrs later at St Monica's seniors, the other end of Fernhill Rd.St Robert Bellamines juniors also went to St Monica's seniors as well.
The seniors closed down about 1963 and they all went to a new school called St Augustines in King Ave, which was demolished in 1990s.
I was born in 1953 in King Ave which is about 50yds from your friends house, and went to all these schools.Anyone who lived in this area and was R.C.would have attended St Monica's, I am 99% sure of this.
You could also try putting a message on Liverpool ex pats, (icliverpool.com) I think. Also on the Bootle message board. St Monica's is also on Friends Reunited
I hope this will be helpful
Cheers Eddy
