If you look at the Gloucestershire Genealogical Database (they hold non-conformists data) - useful for other FOD births etc.

and search for Jasper FOWLER

you will find the they were non-conformists, and Jasper & Hannah's children's are listed including Humphrey 1822 & Samuel - also John Porter FOWLER - 1818 (hence John P FOWLER named later)

click on the surname - and each child's name comes up with parents etc.

at the moment on the 1851 census for Scotland (Ancestry haven't been allowed to provide the whole census)

I can see a John P FOWLER, age 2 in Berwick, Glasgow St John, Infantry Barracks+ also in this Infantry Block

Jasper FOWLER, (Private) age 14, born Sodbury, Chipping, William FOWLER, Private Infantry Block, age 19, born Chipping Sodbury and Amelia FOWLER - 7 months.

On later census, Elizabeth RYAN says she was born in New Windsor, Berkshire c1832

1841 Census, Berkshire, New Windsor, District Infantry Barracks, New Windsor (1st Battalion the 60th?)

Mary RYAN, 16 - not born in County - says born Ireland
Eliza RYAN - 9 - not born in County
Ellen RYAN 3 years and 4 months - not born in County

so it's a military/Scottish background to your family, hence problems with marriages etc.

Hi Karen, Last week I purchased two victorian photograph albums from Stroud which appear to have originated from a branch of the Fowler family. The smaller of the two albums includes [see list below] 44 carte de visite photographs circa 1860-70 many annotated in pencil. The larger album contains later circa 1880-1900 cabinet cards & carte de visites.

These may be of interest in your research.

Regards

Chris
