Parsonage in Cheadle

[Sue Finn]

I have a Samuel Parsonage who according to all the census records that he is on was born in Cheadle about 1818 but I cannot find a record of his birth.His parents were Henry Parsonage and Maria Westerman who were married in Manchester Cathederal in 1815. There was also another son James but I do not know where he was born in about 1820 ne died tragically in 1842 According to the 1841 census Maria Parsonage was dead and Henry had married again and had yet another son John with his second wife Margaret. I am looking for the death record of Maria Parsonage and the birth record of Samuel. Can anyone please point me in the right direction?

Regards
Sue
