Not so quick to throw in the towel on this. Yes this is a tough question. I was hoping other researcher's with experience with New Madrid, (MO) during these years could provide some insight. Thank you for your quick reply. When in New Madrid, Fr. Gibault reported to the New Orleans Diocese. Any chance that Fr. Gibault's records were sent to the Arch Diocese at his death in 1804? It was 6 years before the earthquakes. Or did the Spaniards packed them when they moved out? I will look into the Biography of Fr. Pierre Gibault by Fr. Joseph Donnelly: published by Loyola University Press in1971.
I hope someone may be able to provide more insight to the records.The 1st church was built in New Madrid 1799. Fr, Gibault had to carry small diaries like in Vincennes to record his daily activities.
