Jon -
I do have some information that bears some resemblance to what you present. What I have:
William YOUDAN, blacksmith of Hatfield and Bearswood Green, baptized 2 March 1768 in Hatfield. Married Ann ------, and had at least four children, including:
* Mary YOUDAN, born 7 November and baptized 8 November 1795 in Hatfield;
died 10 November and buried 12 November 1795, in Hatfield.
* William YOUDAN, baptized 29 December 1799, in Hatfield, "the fourth child of
William Youdan."
William was the son of:
Thomas YOUDAN (or YOUDAL - a variant spelling), a farmer of Hatfield Woodhouse ane Bearswood Green, baptized in Hatfield, 2 August 1729, and died in Bearswood Green on 16 May 1781, aged 52 years, buried in Hatfield on 17 May 1781. He married in Hatfield on 1 January 1758, Mary WILBURN, daughter of Matthew, a blacksmith of Hatfield Woodhouse, and Hannah WILBURN. They had at least 10 children:
* John YOUDAN, baptized at Hatfield, 12 August 1758; buried there, 19 Nov 1758
* Thomas YOUDAN, baptized at Hatfield, 25 April 1760; married Jane WOOD,
22 October 1795, at Hatfield. She was buried at Hatfield, 19 January 1841,
aged 88 years, the "widow of Thomas Youdan, of Misson."
* Frances YOUDAN, baptized at Hatfield, 4 December 1761; buried there,
26 October 1763
* Matthew YOUDAN (possibly), a bricklayer of Hatfield and later Bearswood Green,
married Hannah DAWSON
* Fanny YOUDAN, baptized at Hatfield, 24 January 1766
* William YOUDAN, baptized at Hatfield, 2 March 1768 (see above)
* John YOUDAN, baptized at Hatfield, 16 November 1770
* Miles YOUDAN, baptized at Hatfield, 9 April 1773
* Mary YOUDAN, baptized at Hatfield, 30 December 1774
* Samuel YOUDAN, born in Hatfield Woodhouse, 15 May, and baptized at Hatfield,
28 June 1778
This Thomas YOUDAN/YOUDAL was the son of John YOUDAN/YOUDALL (1702 - 1776) and Frances WOEMACK (d. 1744) of Hatfield Woodhouse. John was the son of Thomas YOUDEN (1666-1723) and Alice SHEPHEARD (b. 1669), of Hatfield. Thomas was the son of Thomas UDALL/YOUDALL/YEWDALL/YOUDAN/YOUDON (abt 1627 - 1672) and Anne MOORE (b. 1634), of Hatfield. This Thomas may have been the son of a John UDALL, baptized in Hatfield, 21 January 1593/4, son of Thomas UDALL/UDEN of Hatfield who left a will dated 30 September 1639, proven April 1640. The will was taken orally, and mentions his daughters Elizabeth (bapt. 1596) and Joan (bapt. 1599), but does not mention John (who was apparently dead by the time) nor any children by John. The name YOUDALE is said to be the common NW West Riding spelling of the West Riding surname YEWDALE (Redmond's English Surname Series). YEWDALE is derived from Yewdale in North Lancashire, where Fountains Abbey had sheep-runs. Fountains Abbey also had grazing fields in Airedale, Yorkshire, and the name may have been brought there from Yewdale. There is also a Yewdale near Coniston Lake in Yorkshire. Lastly, there is a village named Yeadon in the West Riding between Bradford and Leeds. The earliest occurrence of the surname is Alicia de YOWDALL in 1379 (Bardsley, Dictionary of English and Welsh Surnames).
Any of this match your info? I have a little more, but this is the bulk. I am descended from Thomas YOUDEN (1666-1723) through his son Joseph (1710-1782).
