Motto: Passibus citis sed aequis (With quick but even steps).
Crest: A stork holding in its beak a Lotus Flower slipped proper. Although a stork is the word usually used, all drawings depict a heron, which is our "official" Crest.
The Coat of Arms: Can be described as follows: Quartered of ermine and azure, in the second and third quarters a cross moline or. This is the achievement that was given to Henry Labouchere and to "the other descendants of Pierre CÚsar Labouchere" on 8 Sept. 1859 by the College of Arms in England. It was already in use by the French and Dutch branches since 1814 and also by Pierre Cesar.
When Henry was created Baron Taunton his coat of arms was augmented with a crown and supporters (two more herons), but that only applied to him of course. Because of the extension of the limitation clause, Henry's brother John and his descendants in the male line are fully entitled to bear these arms. (This was confirmed to me by the college of arms a few years ago).
