Sorry to raise a very old topic, but I believe one of these David Rowland(s) is "my" David Rowland.
Took me a while to make all the connections due to the variety of spellings of Rowland (Rawland, Roland, Rowlands, etc) so wasn't quite able to quite connect the dots on the census records until today. I could only really confirm a South London and Hackney/Shoreditch connection initially until about an hour ago.
To cut a long story short, I am now looking for a David Rowland b, 1823, supposedly in Bala, though most of the census records just said Wales. His father, according to his marriage banns (in 1847, Bethnal Green, to Sarah Ellis, b. 1819 Felsted), is David Rowland, Farmer.
I found an 1841 census which might be a match with Rowland Rowland as a brother, among many others, and mother Margaret - but not sure if that is my David Rowland. Presumably father David the farmer is missing because he'd died a few years prior to 1841 (youngest son is listed 3 years old, putting a death around 1839-early 1841). If I can get confirmation that Margaret's missing husband is David Rowland then I suspect I have a match.
Does this tie in with any of the David's mentioned above, or based on other Rowlands in the area at this time?
