Did you get his Birth certificate? that would give you his parent's names and possible a more definate place of origin.
You might find him on the free BMD,(though it starts in 1837) or LDS site. Also, if you can get his marriage certificate, and the name of his wife, that might open more avenues. Of course, the best way to ensure you have the right JohnFrankish is to work backwards,BMD certificate by certificate, and also check for the family on the censuses. This waycan find out what your family member's occupation and address was.
There are also directories you can search in. Sometimes it takes time and effort, but often the hard work is worth it. http://www.historicaldirectories.org/http://www.historicaldirectories.org/
Eg. there is a 'John M Frankish' in the Slater's 1895 directory, living in Longsight Manchester he is a boiler inspector. My Frankish lineseem to have come from Hunmanby Yorks.( 'Whitby' is also a place name mentioned) Some of themmoved to Manchester, Lancs. I guess they went where the work was.My William Frankish was a 'master bootmaker'(He was also a Lay preacher and aherbalist.) This John, mentioned in Slater's, may be connected to my William Frankish as he was living very close by. Maybe they were brothers? I have been looking at other roots and have somewhat neglected the search for my Frankish line for a while. Good hunting! Jean
