many businesses, trades & occupations can be very useful as they appear in old street listings and trade directories (e.g. Slater's Thom's etc) - unfortunately labourers are not included in these, so no help from that angle.
The problem with Bartholomew's birth is that it is before Civil registration started in 1864 - so to progress you will need to know a location for his birth, ideally a parish, and his religion.
