I have a Birthday Book from 1887 that contains the signatures of 16 Le Poidevin, 13 Mahy, 8 Robin and 6 Ogier.
These Le Poidevins lived on Braye Rd. Parents John & Mary. Children Mary A., Julia C., Emily L., John A. & Selina A.
Other L.P. signatures are Julie Cohn, Lydie C., Job, Thomas, Alfred,Jean, Emma, Pierre Henry, Judith, Gracie.
The Mahy signatures are Ada, Aline Rachel, Alice Marie, Constance Louise, Emilie, Emily M. & Adele, Emma, Florence May, Louise, Mary H, Nicolas, Rachel S, and Thomas.
The Robins are Alice M, Amy, Emile, Ferdinand, Ida M., Martin Henry, Mary E. and Vera.
The Ogier are Daniel M, John A., Julia A, Julia, and Thomas.
It is a beautiful little book and was presented to an American cousin, Ida, upon her visit to Grand Fort. The American connection is defunct and I think that it would be best returned to Guernsey if any family member is interested.
