Edward Thomas Ambrose in 1897

1901

Edward T Ambrose 40 born Hemel Hempstead
Frances Ambrose 51 born Hemel Hempstead

Oh yes and in 1891 Edward is a lodger with Thomas & Mary A Lovett

This FRENCH family are proving very elusive in 1901  I've tried as many variations as I could think of but have still drawn a blank 

Frank Francis French born c1858 Brighton Sussex
died 1927 Eastbourne

Fanny Emily French  born c 1872 Selmston Sussex
 died ?

Louisa May French?  born c 1898 Eastbourne
died 1982 US married surname (MAIR) born 26 Feb 1898

Winifred Emily French (mmn Turner) born c 1900 Eastbourne
died 1981 Eastbourne married surname (SPOONER) born 15 Aug 1900

Are either of these Fanny’s death entry? Or did she remarry?

Mar 1919   Eastbourne   2b 134            
Fanny French   age 49      
   
Mar 1939   Eastbourne   2b 148            
Fanny French   age 64

The only reason I can think of as to why Frank F French would not be on the 1901 census is perhaps he was serving in the Army  Or were the family abroad at the time of 1901 census but their son Frank Jnr. was born 1902 Eastbourne, perhaps they have just been missed or their surname very badly transcribed 

As previously mentioned the marriage certificate would be helpful in confirming father's names, occupation etc....obtaining Winifred (1900) or Frank (1902) birth certificates would give you their fathers occupation perhaps different from 1911c and their address in Eastbourne either side of 1901 census then you could check Electoral Register or try searching 1901c using that address.

I found all the other childrens birth registrations apart from Louisa's but there is this entry...am wondering if she changed her name

Name Gladys May French
Registration Year 1898 Registration QuarterOct-Nov-Dec

I wonder if the oldest daughter Louisa May is

Louisa May Turner born Jun 1899 Eastbourne

Have you got the 1901 census for Frank or Emily?  Not finding Louisa at present.

I don't think the birth entry for Gladys May French is your Louisa May French
I believe she belongs to this family and Gladys May can be found with her family on  1911c
