Hi David/Tricia
Someone else listed the marriage of David Webb on the Gloucs Forum.
As he was noted as only 20 on the 1841 census I dismissed it but looking through the following census years he would have been in his mid 20's and he did have a daughter Sarah aged 5 then.
In 1851 and noted as living in Oxfordshire he has children Sarah 14, Alfred A 10, Samuel 5. Ellen 4 and Lucy Allis 3mo.
I know of other information pass this date but will ask if someone can look up the marriage details on the Glocs forum.
Thank you both.

Cheers Sandy
