One interesting thing was the occurrence of Spanish names of people marrying my French ancestors. They were easy to trace back, and often led back to ships from the Canary Islands.
The history here is that at the time of the American Revolution there were British garrisons near New Orleans in the Baton Rouge area. Louisiana belonged to Spain, which was not on good terms with the British. A fear that the British would attack New Orleans either through the Mississippi River from the Gulf of Mexico or from the garrisoned troops in the area led Spain to recruit and send troops from the Canary Islands, its southernmost province off North Africa. There was a second purpose, the intent to build the Spanish colony of Louisiana, so entire families were sent. A total of seven hundred troops plus their families left on seven ships. One of the seven ships encountered a British fleet, and diverted to Cuba. The other six brought troops to Louisiana. They were scattered along the coast as coast watchers, and stationed on the Mississippi River to defend New Orleans.
Governor Galvez, also a general, marched against the British in Baton Rouge, a feat allowed by the arrival of these Canary Islanders. Here the French branch of my line also gets involved. Those French speaking people evicted from what is now Canada had arrived about a decade earlier, and remembered their harsh treatment. They volunteered to join the fight with about six hundred taking part. Galvez easily prevailed, and later took other British forts, including Vicksburg. Had the British taken control of the Mississippi River the outcome of the war could have easily been changed, And had the French speaking Catholics not been forced from Canada, perhaps the British could have prevailed against Galvez.
This history answered a question that came up in my ancestry search. Several people had done a search to proof an association with the American Revolution, but Louisiana was under the control of Spain. I did not realize the Spanish and their new French citizens were so important in the war.
