War in 1838?

As I was perusing my cemetery photos, I came across a couple of a large, bench-oriented monument in Rome Cemetery, Rome, NY.

I took a closer shot of the epitaph for the husband of the pair, and a question came to me...

Our father, patriot War 1838, freedom

of slaves, philanthropist, inventor,

advocate of Maine Law Prohibition.

...what war in 1838? A basic Google search turned up various things, but the last descriptor suggests to me he was involved in the Aroostook War ("war," it was undeclared) between the U.S. and Britain over the Maine/Canada border. Who knew?
