Hi,
First I would like to point out the Danby Wiske and Danby in Cleveland are two different places and not near each other.
There is a marriage for Francis WATSON and ANN CLARK in Ainderby Steeple 26/12/1835. Both are of this parish and witnesses are Joseph PRATT, Ann WATSON and James MILBURN
William CLARK (son of George CLARK and Jane HOBSON) is in Thrintoft, Ainderby Steeple with, presumably, his second wife, Elizabeth in 1841 and 1851 census
Children of William CLARK and Hannah baptized in Ainderby Steeple are
Mary, 25/2/1816
Ann, 31/1/1818
Alice, 20/2/1820
William, 3/11/1821
Bartholomew, 21/9/1823
George, 15/6/1825
Hannah, 6/5/1827
John, 7/2/1829
Robert, 3/10/1830
Elizabeth, 1/7/1832
Henry, 22/3/1834
Margaret, 24/11/1835
Eliza, 31/1/1837
All children of William and Hannah Clark, labourer of Thrintoft, Ainderby Steeple
So presumably Hannah died between 1837-1841 and he married Elizabeth who is with him in 1841 and 1851. There don't appear to be any children to his second marriage.
Children of George CLARK and Jane HOBSON born/baptized in Danby Wiske are
Ann, born 28/7/1787, bapt. 30/7/1787
John, born 5/9/1788, bapt. 8/9/1788

Hannah, born 4/4/1803, bapt. 8/4/1803

All children of George CLARK (described as cottager and then husbandman) and Jane HOBSON, dau. of John HOBSON of Danby. Some of the baptisms give the address as Crawford House. Jane's father John HOBSON is described as 'deceased' for the first time at George's baptism in 1796.
I'll let you sort that lot out. If you need any further information, please get back to me
