I realize that this link has been completed, but my g g g grandparents were William Mawby and Elizabeth Matthews and I have read all the 17 pages of everyones thoughts and wondered if anyone can help me. 

- Did anyone find out who William Mawby's parent were?
 
- Could Frederick have been the son of one of William's sons, William or John and not William senior?
 
- Richard Mathews, 1745 was said to have married Dorothy Macwheber in 1769.  I cannot find any Macwheber's anywhere and wondered who found this and where they got this information.
 
- behindthefrogs wrote on Feb 10, 2012 that Elizabeth, daughter of Richard and Dorothy would have been 38 when she married William Mawby, but according to me Elizabeth's dob was 1786, which would have made the marriage date as 1824 not 1814 and William jr was born 1817, john born 1819. 

I'm a novice at this and am using findmypast.com as well as freereg, but I am at a loss to know where you find all this information.  Are there any other free websites I can use?

Looking for anyone who might know the wife of my great grandfather Alfred Mawby of Long Lawford born in 1852.  On the 1891 Census it states his wife as Maria who was born in Wolston(e).  When I pull up the marriage of Alfred, the only one that comes up is to a Charlottey Whittaker in 1879.  I can't seem to find out who his wife was as I can't find any Maria or Charlottey Whittaker in any census who was born in Wolston(e).
