It is George Bowring estimated year of birth 1805 I think
I think his age in 1851 has been misread by Ancestry's transcribers as 46, but it is written 26 -- compare the figure 4 in Gwenllian's age on the line below? It's always best to look at the original images, if you can, because the transcriptions may contain errors.

Lympsham is nothing more than a guess, based on what can be found online for that name. It would be best to order the marriage certificate as suggested above, to get his father's name/occupation.
