Therefore, there might be more children from this family that we don't know about. George had five with Esther and two more with his last wife, Sophia SANTER (1831-1914). See more about George's families in a previous post here.
Now, I thought that solving this would be easy. Look for marriages for George in Uckfield before 1849 when he married Esther. EUREKA there is one! BUT, the marriage registration page for
the December Quarter 1844 has four possible spouses.
There are three DAWES births in Uckfield between the marriage date of 1844 and Elizabeth's assumed death date of 1847 (2 in Mar. 1846 and 1 in Mar. 1847) that could be attributed to George and Elizabeth. Although, there are no children who are unaccounted for in 1851 unless they were living with extended family, maybe the HARVEY's.
Now, to try and find the HARVEY family in the census.
NEWS FLASH: I checked my research spreadsheet that I enter all my B,M,D notes into and found a marriage between George DAWES & Sarah PECKHAM registered in Holy Cross Church, Uckfield 01 Dec 1844. So Elizabeth was the wrong choice!
