Hi,

I don't know if you have seen this record. They seem to be located in the 1850 census index - under a mispelling:

CHEVAL, DONDLIEN*
State: LA Year: 1850
County: Orleans Parish Record Type: Federal Population Schedule
Township: New Orleans 7th Ward Page: 373
Database: LA 1850 Federal Census Index

2 children are listed with them, a daughter 8, and a son Henry - the script is hard to read, but the wife is definately Louise.
