Hi
I don't know if this will be of any use to anyone but I'll throw it into the mix anyway...
I found a marriage of Mary Ann Nowell to Samuel Hamling 2/6/1848 at All Saints, Brixham. She was a spinster, of full age, the daughter of Nicholas Nowell, mariner. Samuel was also a mariner, son of Richard Hamling, thatcher.
In 1851 Samuel age 24 and Mary Ann age 28 were living on King Street, Brixham with 2 year old daughter Mahala (think this really refers to Amelia), and 1 year old daughter Sarah. Next door was Nicholas Nowell, widowed, age 51 and his married daughter Betsey Nowell age 26.
By 1861 they are living at Ramscombe, Brixham and Nicholas has moved in with them, they also have more children: Samuel age 9, Susan age 7, William age 5, Richard age 3 and Cornelius age 6 months.
In 1871 they have moved again and were living on Pump Street, Nicholas is no longer there. Samuel is a fisherman, Mary is a baker.
Some of Samuel's brothers and his parents had moved to Hull by the 1850's and were fishermen/mariners.
It is possible that Samuel's bride, Mary Ann Nowell, is the same person as the 15 year old Mary Knowell who on the 1841 census was a domestic servant and living in the household of Samuel's parents Richard and Elizabeth Hamling in King Street. (At that time Richard was a baker).
Also Samuel's mother Elizabeth (nee Coke) had a sister Susannah born in 1781. She married Edward Rouse 28/9/1800 at St Mary's, Brixham.
Could this be a connection to the Rowse family??
Anyway hope this is of use to someone!
