The first census of England, Wales, Scotland and Ireland took place on 10 March 1801. The names of the people counted then were not usually kept. The list that follows includes most, but probably not all, of the Howcutts who should have been included.
Most of the ages shown are not exact but have been calculated from christening dates or from ages recorded when people died or were buried. For one of the George Howcutts, the age is estimated from the date of marriage and age of his wife when she died.
The places shown are those where it is likely that the person was living in 1801 but are probably not correct in every case.
