Should "aunt" be capitalized in this sentence?
Jan's aunt Cindy took a ceramics class.
Should it be - Jan's Aunt Cindy or Jan's aunt Cindy?
If you could replace “Aunt Cindy” with a proper noun (e.g., simply “Cindy”), then it would be fine to capitalize it:
Jan's Cindy took a ceramics class.
That might be acceptable in some contexts, but certainly not usually. It would be more common to write “aunt” in lower case:
Jan's aunt Cindy took a ceramics class.
In this case, “Cindy” is in apposition to “Jan’s aunt”.
You generally only capitalize "aunt" and "uncle" when they're being used as part of a proper name. For instance, when writing a letter, you might start with "Dear Aunt Cindy". Or when referring to her among your siblings, you could say "Aunt Cindy is recovering well from her operation."
But in the phrase "Jan's aunt Cindy", it's not being used as a name, it's just describing the relationship", so you don't capitalize it.
You can see similar style with other family relationship words. Referring to a parent, you would write "Hello, Mother" (capitalized because you're using it as her name) but "I got money from my mother" (lowercase because you're just describing a relationship).
The sentence would also make more sense if you inserted some commas:
Jan’s aunt, Cindy, took a ceramics class.
