Overall, especially with respect to the region, Camlin overall (Fells, Way, and Shore) are fairly open-minded folk. They don't hold much intolerance toward various folk like some of the area, there's no prejudice against the halfling, nor do they hold any disdain for half-elves or half-orcs persay, and they're amiable toward the localized fey.
Sure, if you're generally a total jerk it's that jerkiness that's the issue and not your race. Very much a meritocracy, but simply so. If you've extenuating circumstances, such as how Talashia's coming across in her early development, there's going to be some fearfulness and what not. Also, if someone stole a baby and replaced it, folks might be made about that, but probably not about the baby. More so, if the baby was left to a couple who couldn't produce a child, then they may be okay with that while some folk might be put off by it.
Basically, the area is overall good folk, but there's always the chance for a bad egg here and there, especially if it helps your story.
