"Anglesea" is a misspelling of "Anglesey", an island off the northwest coast of Wales. As such, it doesn't have its own distinct meaning; it's simply an error. Think of it as writing "teh" instead of "the" -- the intention is clear, but the spelling is wrong. Therefore, it's important to be accurate when referring to geographical locations. Avoid using this form, it is not an accurate term.
