From the two pictures, it would appear that your bottle is French, dating to the 1810-1830 period. I could tell more with a picture of the pontil. These are not uncommon today, nor were they in North America during their period of use. There is a direct and traceable lineage from the early 1700's French flowerpot bottles all the way through the later 1800's period champagne bottles.
Here is the bottom. It has no seams. As you can see its neck twist as it was pulled and blown. There are large bubbles in the glass. The top is unusual looking compared to our John Ryan & James RAY Bottles.
