The census information has the date when the census was taken.
i.e. depending on that it might actually only be 2 years out
If you're sure that's him then that would be a good birth certificate to get. Might be the only way to find his parents, then use the 1841 census to find more about them.
Not totally sure it is him.
There are 2 with the same name ( Isaac Kelsey )
Prime suspect is born Dec 1848 in the district of meriden plus he ties up with a death record in 1912.
No2 is born in 3rd Quarter of 1846 in the district of foleshill ( no death record as yet ).
However it is these birth districts that are confusing me a little.
Confusing me more however is that in all the census only 1 Isaac comes up the same one all the time with a birth year of abt 1849 in Fillongley.
No1 is closer in birth to the census ( only a month out ) but the district is wrong ( unless Meriden is part of Foleshill )
No2 is more accurate in district but nearly 3 years out on birth.
I checked the death records in case one of them died as an infant but there is nothing there to suggest they did.
Don't really want to get wrong certificates.
Any thoughts?
