Birth of Alick Croucher in FreeBMD in October-December 1897 in Southampton (2c 41)..
In the 1901 census as Alick Croucher aged 3, born in Southampton, and living with his parents (George and Alice), five brothers (Abert, George, Harry, Walter and William), and two sisters (Alice and Ethel) at 23 Balham Street, Southampton St Mary, Hampshire.
There are numerous entries on the Ellis Island Site for Alick (Alec, Aleck) Croucher aged 23 in 1922 and unmarried and aged 26 and married in 1924 on several different ships (Aquitania, Homeric, Mauretania) all leaving Southampton so I suspect he was one of the crew. I have not found the entry for his marriage.
Matt Shepherd has an entry in Ancestry Public Member Trees for Alick Croucher born in 1898 in Southampton St Mary, Hampshire, parents George Croucher and Alice Maud M Oakley. Philip McCauley has similar information adding the 1901 census.
