You would need to check the parish records for Aston Juxta (I don't have them). Unless someone else has them, it will mean a visit to B'ham Library. If you aren't local, then if someone is going to the library, they may be able to do the lookup for you. If the query is still outstanding towards the end of the week, I will probably be going, so I'll do it then.
I think that it is unlikely that you will get the maiden name of the mother on the baptism record - but you may get lucky and get the actual date of birth on the record. You will also probably get the father's occupation and residence.
I have used IGI to see if there were any siblings baptised around that time at Aston Juxta and it doesn't look as if there were.
