Birth of Florrie Croucher in FreeBMD in January-March 1900 in Hatfield (3a 684).
In the 1901 census as Florrie Croucher aged 1, born in Hatfield, Hertfordshire living with her parents (Arthur and Ada Marion) in three rooms at 20th? Mile Cottages, Hatfield, Hertfordshire.
Philip McCauley has an entry in Ancestry Public Member Trees for Florrie Croucher born about 1900 in Hatfield, Hertfordshire, parents Athur Croucher and Ada Marion Kerry.
I cannot find any later information. Note that a Florence Croucher was born in Hatfield in 1901, parents Arthur E and Eleanor Croucher and it is this family that is in the 1911 census.
