I found a Dreux,Guillory, age 5, in the 1860 census of St. Landry, but his parents are Augustin Guillory and eugenie Soileau. There is an Achile age 21. He is living with Eliza Bondick, age 51 and some other Guillorys. One other is Achile age 12. Parents are Valcourt Guillory, age 39 and Pauline Bordelon 38. These people are too early for your grandfather, I am sure. What are approximate dates?
