Corenlius Whitehead was at Gt. Finborough from 1844-1864-ish). His son joined him at some point, and they crossed paths with the law several times between 1857 & 1864 (for minor offences) and were put on trial in 1864 for "Wholesale Plate Theft". Cornelius was cleared, but David was sentenced to 6 months' hard labour and Maria Whitehead (Cornelius' wife) was give 9 months hard labour.
A few weeks later Cornelius joined them for assault. He sold the wind & steam mill at that time.
Cornelius reappeared at Botesdale (milling) in 1872, along with a Thomas Whitehead (1864-1872).
During his fateful stint at Great Finborough he was also linked a mill at Stowmarket (1844-1847).
David went to Somesham (1873) where he kept a beer house and mill. In 1877 he was charged with sheep stealing. He then did 12 months' hard labour. and dropped from my milling records
I hope this helps, even if its many years later than your first post
