Joseph Hayes son of Isaac, broker of Bethnal Green, appr. to John Lehook on 5 Mar 1744.
This date is for the binding of apprentice to master -- the apprentice is usually about 14. Joseph doesn't appear to be in the freedom admission papers index (though that index has lots of problems) so may not have completed his apprenticeship.
A quick index check didn't show a birth for this Joseph, but there is a death of a Peter Hays, son of Isaac, Bethnal Green 13 Apr 1747, so 'Peter' seems to be a family name.
Note that this is probably a fairly well off family.
