There's an oral history of my paternal great grandfather coming from Scotland and marrying a Cherokee woman right at the time of or just before the Trail of Tears time... 1835 or so...

I am a student of the Bible and learned some Greek in Bible School but also wanted to be able to ferret out the roots of the Old Testament...and the more I learned about the Hebrew language, the more I desired to learn it.

One of the best books if it is still around, for learning English grammar is English 3200. It is a workbook in a different style and easy to go through. It reinforces what you just learned as you go farther, giving you the answer on the back of the next page even. There is one for high school level and one for college level, or there was.

I also know American Sign Language. Again, a visual language. The Cherokee syllabary and the Hebrew alphabet are quite similar (and indeed the Hebrew symbols were the basis for Cherokee symbols.) But I "see" Cherokee and Hebrew as much as hear it... I am a visual person. I think I was just "cut out" for language and wish I had begun much earlier to study them intensely.

Update: I see the English 3200 is updated and around (mine is from 1972 and does not have "writing applications".) This one is by the same guy, so I'm sure it will suit your needs, if you wish to try it. (See if you can get the library to track one down for you first?)
