I found a marriage record for Edmond Caruthers and Oliva Comeaux in Acadia Parish. They married 2/10/1892 [certificate #00531].
On the 1880 census for St. Mary Parish, I found what may be Oliva. She is listed as Olla V. Como, age 10. The father appears to be deceased. The census reads:
Desire Como 46 [female]
Lillian Clare 11
Olla V. 10
Jane R. 8
I tried finding this family in 1870 and was unsuccessful. I was hoping to find the name of the father.
I found Edmond Carethurs on the 1880 census for St. Landry Parish. The father is apparently deceased. The census reads:
Modest Carethurs 35
I found the 1870 St. Landry Parish census for the family of Edmond Carothers who was not yet born. The census reads:
Edmond Carithur 31
Rosa 4 months
On the 1860 census I found what I believe to be Edmond [the father] off in another parish working.
On the 1850 St. Landry Parish census, I found Edmond [the father] living with his father, Samuel Carothers [55, planter] and his younger brother, Cesaire . Edmond is 18. No mother is listed.
If you live in Louisiana, I suggest that you use Father Hebert's sacramental books [a huge set with many volumes] to get dates for births/baptisms, marriages and deaths for all these ancestors. The books should be at most libraries.
