Yes Rex I do know a bit about John - his 40 year spell as Minister at Colne Particular Baptists, his involvement in the founding of Haggate Baptists, his brother Thomas' involvement with Salendine Nook at Huddersfield, his descendents in Briercliffe and Harle syke including Jack Stuttard, his brother Thomas' descendents in Banbury and later as noteworthy pioneers of northern Tasmania, his father and brother both named Jabez etc but even so i still intend to purchase a copy of your book in the very near future - watch your post
This particular colony of Stutterds are very well documented though I do know of quite a few errors in the previously published material about them. For example in works abour Baptist movement in Barnoldswick John's father Jabez was described as Scottish - this is quite false i have details of his baptism ca 1707 and his parents (another Jabez!) marriage in Keighley a few years before this.
This contrasts sharply with my own Stutterd deadend - Richard Stutterd also Southfield born 1779 or 80 who married Mary Amelia Mason in St bartholomews in 1800. His baptism is not recorded so i cant find his parents but would be amazed if he was not a direct relative of John, Thomas and Jabez the famous diary writer. If you have seen Peter Walsh's articles on the Pendle LFHS newsletters about the Diaries of Jabez Stutterd then it is me he is referring to as contributor of further details since his original transcription of the material in Colne library into book form.
Those 3 brothers John, Thomas and Jabez have inspired a lecture tour as well as some significant academic articles in the University of California. many of Thomas' letters to his brothers and descendents survived to form the basis of these various works.
Incidentally I have seen recently a recommendation for your book which states that John Boothman Stuttard Lord Mayor of London is a descendent of John the baptist minister (in the recommendation not in the book - I dont know if you were of this opinion or not). This is incorrect. John Boothman descends from Hartley Stutterd of Southfield quarryman of Catlow son of my ancestor Richard and not from Hartley Stutterd of various farms around Extwistle and Worsthorne who was indeed John Stutterd's son.
