Farmeroman, you are researching same family I am - insofar as my ancestor Jean-Baptiste Marie Pontet married 16/05/1789 St Eustache, Paris 1e, with Charlotte (Marie) Augustine DERHEIMS, daughter of Pierre DERHEIMS (1752-1783) & Margueritte Charlotte GAUDOIN (no dates yet), the latter daughter of Jacques GAUDOIN & Geneviece Madeleine PREVO(r)T (latter signed a document 1769 as PREVOUTTE GAUDOIN). Margueritte GAUDOIN's sister, Genevieve (1745-1810) was Superintendent of Mrs Pugh's boarding school for girls at Great Baddow, Essex. I have her will from the (then) PRO and a typed transcript. I attempted to attach to this message, but it won't accept doc or pdf. If you'd like to have these, you can contact me at
patrick@pontet.com. I also have a (current) one-page tree of the DERHEIMS-GAUDOIN connection from Jacques & Genevieve's generation to Charlotte DERHEIMS who married J-B Pontet (same generation as the Marie Antoinette GAUDOIN (1779-1866) you have mentioned. I suspect Marie Antoinette was one of the two daughters Minni & Lizette GAUDOIN mentioned by Genevieve GAUDOIN in her will of 1806 as being her nieces, daughters of "my brother Antoinette GAUDOIN ...." who owes her "for what she paid for the education of his children, and if the sum can be obtained, I give it to my nieces Minni and Lizette GAUDOIN".
Through you exchanges on this site, you've given me at least a little extra info on this family, so thank you for that.
I hope some of this helps. Patrick
