I have a feeling that you won't find records on line. Alderney, though beautiful, is about 20 years behind the rest of the British Isles!
According to the book I have in front of me right now -
...... "Registers of births and deaths in Alderney from 1850 and of marriages since 1886 are preserved in the Registry for Births, Deaths, Companies, Land and Marriages in St Anne (the capital), whilst the registrations on Alderney since 1925 are housed in the Royal Court House, in St Peter Port in Guernsey. There is a gap in the registrations between 1940 and 1945 (the German Occupation), and some other records no longer survive before 1945 because they were left behind at the time of the evacuation of the islanders before the Occupation and were probably burnt. Mrs E. Mignot of St. Martins has transcribed all the island's entries and you are advised to write directly to her for any searches. The Priaulx Library holds microfilm copies of birth registrations up to August 1885, and of death registrations between 1850 and 1855 and from 1907 to 1925....."
The address for Mrs Mignot is 8 St Martins, Alderney GY9 3UB.
The address for the Priaulx Library is Candie Road, St. Peter Port, Guernsey GY1 1UG. Tel: 01481.724512. website:

I can tell you that the name Bott is well known on the island, with at least one road (Rue Colin Bott) named after the family.
Good luck with your search.
