In the 1841 census as Elizabeth Croucher aged 15, born in Hampshire and living with Issac (father?) and Elizabeth (mother?) at Cox Hill - note there is another Elizabeth Croucher of the same age, daughter of Isaac and Harriet, on the same page.
There is an entry in FreeBMD for the marriage of Elizabeth Croucher and James Manson in January-March 1853 in Lymington (2b 681) which included Boldre.
I cannot find any other information.
