Hi
Are you sure he was baptised or are you assuming he was?
What actual date was he born in 1901 - his birth was only registered in the December quarter so he was born between October - December. If he was baptised - it could have been 1902?
Which church was he baptised in?
Several churches in Chelmsford and baptisms could take place weeks, months or even years after a birth so without more precise info it would involve a lengthy and possibly fruitless search through parish records
As you know his parents names - what information are you looking for from a possible baptismal record that isn't available on his birth certificate?
