John,
Have you had a look at the Bishop's Transcripts for Dearham? Visit [
www.reayw.freeserve.co.uk] There are lots of Ritsons in there. I've just had a quick look but can't find Robert in the 1825 records. There is a Joseph Ritson son of John and Jane baptised on 24th Sept 1825. Also, very strangely a Joseph Ritson infant buried two days earlier!? These records are well worth a visit. The Ritsons in Dearham go back to 1664 "November 27th was John ye sonne of Robert Ritson baptized".
Hope this was useful.
