* Paul and Eli were twins

I also have a record of Jean Baptiste, the father of these children Bapt. Record
Baptism: 6 Feb 1745-a son, Jean Baptiste was born at New Orleans.
" In this year seventeen hundred forty five and on the sixth of the month of February, I the undersigned Capuchin Missionary Prist. Baprized with the ordinary ceremonies of the Church, Jean Baptiste legitimate son of Jean Baptiste Champange and of Magdelain Challier, and standing for godfather, Rene Chaneler and for godmother Maqrie Ann Piequary"
I am from Evariste's line
Hope this helps.
