Dobfarm, I agree. My line backward from William Hartley born Ovenden in 1792 and died 1868 in Haworth. Before moving to Haworth circa 1816-1818 my William was in Wadsworth (using Birchcliff Baptist) but when he married the first time in 1814 to Betty Asten at Halifax he was in Northowram. He & Betty Asten already had a daughter Mary pre-marriage in 1812 and a Grace soon after marriage. William's brother Barnerd was already in wadsworth and had the same occupation as a tinner. William was born in Ovenden and baptised at Warley Independent Chapel in Warley Town. His parents were Barnard & Betty (nee Brigg married 1770). The family start out at Upper Oldfield in Warley using Mixenden Independent Chapel. Barnard & Betty die at Haley Hill, Northowram and were buried at Salem Methodist in Halifax in 1828 & 1837 respectively. There is a newspaper article that mistakenly suggests the 1828 death is Barnard Hartley the bridge builder of Pontefract. You can't even believe the papers in 1828! I don't know what happened to the graves at Salem Chapel when the road was altered in the 1960's(?) but fortunately a record of the inscriptions exists in Halifax Archives. I say all of this to demonstrate how the family moved about the district and also their use of various non conformist chapels. I must point out that the Northowram Independent Chapel is listed on the LDS IGI under New Malton, York! Having looked at the register entries on BMD registers it looks like the register may have been taken to Malton from Northowram by someone, possibly a Heywood connection here. Apart from the register entries, the links between members of this family have been substantiated by various newspaper family notices in the Leeds Mercury and Halifax Guardian. The fact that John & Joseph, 2 of the siblings of my William, were involved in book binding, printing and newspaper publishing must have contributed to the newspaper entries. This follows later with an indirect link from the aforementioned John to a John Hartley who starts the Brighouse Echo. Enough said, it is mostly on Malcolm Bull's site.
The use of non conformist chapels was a bit of a surprise to me given that they descended from a curate of the Church of England, namely Rev David Hartley, but David was school master at Oliver Heywood's Northowram chapel and must have been sympathetic towards non conformism.
Going back a generation from Barnard, he was born circa 1751 the son of Barnard Hartley & Betty nee Hyde that marry at Halifax St John in 1735. They have children locally; John 1736, Hannah 1738, Thomas 1745, Mary 1747, Sarah 1749, Barnard 1751 and possibly Joshua 1754. Latterly they are in Warley Township and using Luddenden. In the gap between 1738 and 1745 it seems that Barnard & Betty were possibly in Leicester & Loughborough where they had Elizabeth 1741 (died an infant and buried there) and David 1742. I have not yet been able to bring forward with all certainty the lines of John, David & Thomas. Not forgetting the female lines which may give rise to illegitimate male Hartleys.
There is information online but, also from my own research, about Barnard's (B1716) older siblings and half siblings that show how they moved away from Halifax. Elizabeth marrying Francis Booth and going to Birstall, David the philosopher to Cambridge (at university), Newark, Bury St Edmunds, London and Bath and John who was an Excise Officer being firstly in Halifax where he marries Mary Holker/Howker and has a son David in 1732 baptised Illingworth, then he is in York and finally Dorking Surrey. Family reasons may well explain Barnard being in Leicester in 1741/42 but it may have also been connected to his work. Barnard was also in Stockport at one time around 1740 as this is referred to in a letter (Halifax Archives) from his half brother Dr David (the philosopher) to his friend John Lister and mentions sending 5 guineas when Barnard's wife leaves Halifax to join her husband in Stockport. The line forward from David (B1732 of John) is not completed either but if he survived that line may be in the south.
There seems to be so many Davids around in the mid 18th century I have not been able to separate them and see where they link in. Of course there is the coiner "King David" as well. One of the incompleted lines will I am sure connect Brian's (firefox1960) David Hartley of Binns Hole, Ovenden that marries Sarah Whitley of Moor End, Ovenden in 1791. Can anyone clarify where Binns Hole (or Binns Owl) is? I have found suggestion that it is near the present Nursery lane in Ovenden which is very close to Bleakbrough (Blackburn?) where the first mentioned above Barnard & Betty (nee Brigg) are living circa 1785 to 1788. It is possible that Sarah Whitley was not David's first wife and he is the one born in Leicester. I have forgotten if there is an age at death of this David.
