Dear keyboard86 and youngtug....
One point: remember, the 1841 census attests that a Henry Dowsell was born to parents Thomas & Elizabeth in 1835-6, not 1841.
Now I must admit that Henry's marriage and death certificates (which I have) give an age which makes his birth to be 1841, as do subsequent censuses which he filled out. However, if the marriage cert is to be believed, both Henry and Margaret were 25 when they wed, so I have gone along with believing that Henry fudged his age in order to appear younger, either for her, or for employment reasons when he migrated to Cardiff, or some other reason like vanity. It happens, as you know! I can see that the Henry Dowdsewell buried 1843 age 7 in Cricklade parish does sound awfully relevant, but it could be a different Henry D I suppose..
Incidentally, Henry D is 'Dowdeswell' on his daughter's birth certificate, 'Dowsell' on his son's and 'Dowswell' on his marriage cert! Couldn't seem to make up his mind, but finally plumped for 'Dowsell" (death cert)
I think there may well be mileage in youngtug's Cricklade parish find: marriage of Thomas 'Poundsell' to Elizabeth Brown 19.12.1826 - which fits the ages of children born to Thomas & Elizabeth Dowsell of Cricklade in 1841 census - and also might explain Esther Brown living with them - Elizabeth's mother? - and Alfred Brown age 5 - son of a perhaps deceased sister of Elizabeth, therefore Esther's grandson?
Henry ('Harry' somewhere) married twice: second marriage being to Ann White in 1873. On both those certificates he states his father to be Thomas Dowswell, a carpenter. 'Deceased' in 1873. Therefore it appears that Thomas died some time between Henry's 2 marriages, that is between 1866 and 1873.
I hope you are both as intrigued by this as I am.
Any further progress would be gratefully received.
