Alabama Landing is on the Ouachita River east of Marion. There is not much there though except a bunch of fishing camps and a boat ramp to the river. I always heard it got the name because this is where lots of people coming from eastern states dis-embarked from boats as they were moving to LA. I really don't know if there was ever much of a settlement there or not or any cemeteries. There is a Cherry Ridge section in Bastrop, LA. I don't know if it's the one your seeking though. By the way, My GG-Grandparents came from Dallas County AL in mid 1840's also. They came by boat from New Orleans and up the Ouachita but they did not stop in LA, they went on to Union county AR where they landed at Champagnolle Landing and settled there for a few years before moving a little farther north into Calhoun County, AR. I know of several families that left Dallas County, AL and settled in Union County and Calhoun county AR. Mine were Weisingers, Garretts and Grumbles.
