I see from the previous answer that Free BMD shows nothing for this date, the only Freda Davey on FreeBMD close is a Freda M Davey born Jan-Feb-Mar 1912 in Colchester , mothers maiden name Munson, so a few months earlier than your July birthday.
Do you have a copy of Fredas marriage record to Prosser Lewis ? on English marriage records the fathers name and occupaton are listed. If you had Freda's fathers name and occupation, i can do a search for him, as Freda is your aunt , her sibling is your direct link, where were they born here, if so what is their name, and other siblings names ? does thier records contain thier parents names ?
Also , if you have a record of Freda's passage, does it contain her English address ?
Let me know and i'll have a look
