Brick Walls - - - genealogically speaking

Anyone who has engaged in the pursuit of genealogy for any amount of time has encountered a "brick wall."

That's the term we root-searchers use to label "end of line individuals," those most elusive of ancestors who seem to have appeared out of thin air because we can't find any documentary evidence of their origins.

Anyway, one of my brick walls has been a young lady by the name of Mary Eliza Robertson. She married a fellow named John Patrick in Wayne County, Georgia, back in 1836. Sadly, she was killed by those dastardly Seminoles who were raiding Nassau County up in North Florida in May 1840. And, that's about all I know of her.

Her widower John quickly remarried to his sister-in-law Linnia Robertson, and the two of them came down here to Central Florida. In fact, they homesteaded land not far from where I live in Apopka.

But, I digress.

Despite many years of digging, I have not been able to find anything about the origins of Mary Eliza. (Or, her sister Linnia, for that matter!)

That is, until today. I think I am finally beginning to assemble enough pieces of the puzzle to at least form the hypothesis that they were daughters of a dude named Josiah Robertson.

Here's a link to the notes I've collected so far. Any input would be appreciated!
