A Fulani village in Algeria

Anyone acquainted with West African history will be aware of the remarkable extent of the Fulani diaspora, stretching from their original homeland in Senegal all the way to Sudan. However, I was surprised to read the following note in a history of the Tidikelt region of southern Algeria (around In-Salah):

"Le village actuel de Sahel a été créé en 1779 par Sidi Abd el Malek des Foullanes, venu à Akabli dans l'intention de se joindre à une pèlerinage, dont le départ n'eut pas lieu... Les Foullanes sont des Arabes originaires du Macena (Soudan); il y a encore des Foullanes au Sokoto; Si Hamza, le cadi d'Akabli appartient à cette tribu." (L. Voinot, Le Tidikelt, Oran:Fouque 1909, p. 63)

(The current village of Sahel was created in 1779 by Sidi Abd el Malek of the Fulani, who had come to Akabli with the intention of joining a pilgrimage whose departure never occurred... The Fulani are Arabs originating from Macina (Sudan [modern-day Mali]); there are still Fulani at Sokoto; Si Hamza, the qaid of Akabli, belongs to this tribe.)

I very much doubt there would be any traces of the language left - even assuming that Sidi Abd el Malek came with a large enough entourage to make a difference - but wouldn't it be interesting to check?
