Montmartre Cemetery in 1824

Although officially opened in 1825 under the auspices of the city of Paris, Montmartre Cemetery had been used for burials since the end of 18th century.  

Lecouteulx de Canteleu in D35

There is a large mausoleum in D35 along chemin des Anglais between Distel (D41) and Couet (D35) that is unmarked except for a large letter "C" above the bricked up doorway. 

 It is located at Salomon 1855 map Ss45.

Salomon 1855 places a Champbel next to "C" at Ss46 in D35. I believe this is George Washington Campbell ((1799-1834), an American reportedly buried in D41 but the Registres journaliers d'inhumation list his grave behind Couet (D35) and just left of a Couteaux de Canteleux. 

It appears that the mystery "C" mausoleum is in fact the gravesite of Barthélemy-Alphonse Lecouteulx de Canteleu (1786-1840), Lecouteulx de Canteleu vicomtesse de Bizemont (died 1828), Mathilde Calhouet madame Lecouteulx de Canteleu (died and/or buried 1850), and Augustine-Mathilde Lecouteulx de Canteleu comtesse d’Anglesqueville (1814-1856).

DLocated in ivision 41, Avenue des Anglais, close to D35. The DBR places the graves together in the vicinity of Tonniges in D41, near Duhamel. Permanent.
