KIMPTON, Hitchin, 17th/18th century
The Parish Registers were official documents which had to be kept in a legally defined manner. If people chose not to use the Church of England (they had no choice in the case of marriages) by going to a chapel, etc., there was no legal need for their family events to be recorded anywhere. Some non-conformist ministers kept their own records (sometimes in the form of a log book of event which could include meetings, etc.) and some of these have survived. Some chapels had their own burial grounds, some may have used the burial grounds of other chapels, and some may have used the parish churchyard.
Virtually all the surviving pre-1837 non-conformist "registers" have been microfilmed and if the information is not there it either never existed or has not survived.
The National Burial Index shows that some Kimptons were being buried at the parish church of St Mary, Hitchin, between 1800 and 1850, although most were children:
24 Apr 1811 William KIMPTON 2
3 Dec 1813 Robert Smith KIMPTON 3
28 Aug 1819 Eliza KIMPTON 2
6 Jun 1825 John KIMPTON 1
24 Dec 1829 John KIMPTON 45
27 Jun 1849 Sarah KIMPTON 70
There are also Kimptons (and variant spellings) listed in Pigot's Directory under Hitchin
John Kimpton, Ironmonger, Cock-street (1823/4) can probably be linked to John Kempton. Brazier/tin-plate worker, Cock Street (1839).
Widow Kimpson, landlord of the Plough, Bridge Street (1823/4) may well have been the mother of Thomas Kempton, landlord of the Plough, Bridge Street (1839).
In addition the 1839 edition shows Mrs Mary Kempton, Bancroft Street, and Thomas Kempson, baker, Bridge Street.
