On February 10 1851, Richard Taylor married Louise Marie Myrthe Bringier (d. 1875), a native of Louisiana, daughter of a wealthy French creole matriarch Aglae Bringier, who would soon help them out financially after the freeze of 1856. Taylor and Marie Bringier would go on to have five children, two sons and three daughters; Richard, Zachary, Louise, Elizbeth, and Myrthe. I have no further info on Richard's daughters. His two sons, Richard and Zachary, both died during the war after contracting scarlet fever, the loss of which hurt the elder Richard Taylor deeply.
It seems Richard's two sons died before the age of 5, therefore a Taylor surname dead end.
