formed a branch in Picardy in the reign of Louis 
XIN Zor, later 
Lamarck’s grandfather, Philippe de Monet, “sei- 
eneur de Bazentin et autres lieux,” was also “chevalier 
de l’ordre royal et militaire de Saint-Louis, command- 
ant pour le roi en la ville et chateau de Dinan, pen- 
sionnaire de sa majesté.”’ 
The descendants of Philippe de Lamarck were, 
adds de Cauna, thus thrown into two branches, or at 
least two offshoots or stems (drzsures), near Péronne. 
But the actual posterity of the Monet of Picardy was 
reduced to a single family, claiming back, with good 
reason, to a southern origin. One of its scions in the 
maternal line was a brilliant officer of the military 
marine and also son-in-law of a very distinguished 
naval officer. 
The family of Monet was represented among the 
French nobility of 1789 by Messires de Monet de 
Caixon and de Monet de Saint-Martin. By marriage 
their grandson was connected with an honorable fam- 
ily of Montant, near Saint-Sever-Cap. 
Another authority, the Abbé J. Dulac, has thrown 
additional light on the genealogy of the de Lamarck 
family, which, it may be seen, was for at least three 
centuries a military one.* The family of Monet, 
Seigneur de Saint-Martin et de Sombran, was main- 
tained as a noble one by order of the Royal Council 
of State of Jume™ 20, 1678., ‘Te descended ((@) irom
