I would like to find any information about the parents or siblings of Martin Farnell, the adoptive father of one of my ancestors, who I believe was born in Coton-in-the-Elms in about 1748. He married Frances Mathews in Melbourne or Lullington, Derbyshire, on 17 Mar 1805. Frances, born in Edingale in about 1771, was the mother of Phoebe Mathews, her illegitimate daughter and my ancestor. On 29 April 1789, Martin Farnell became the high sheriff of Derbyshire until 29 January 1790, which seems slightly unusual because in most cases they were appointed from January or February for about a year.
I have not so far been able to identify Martin's parents or siblings. It's been a few years since I really searched for this, and I was wondering if any useful online records, e.g. parish records, might be available now, which might have this information? I'm assuming he was born in Coton-in-the-Elms, but he might have been born in another nearby locality. I seem to remember seeing the Farnell's mentioned in places like Ashby-de-la-Zouch, possibly as bankers. Martin later declared bankruptcy. I also have his will, which indicates that he had adopted Phoebe.
Thanks,
Alan
