Is Their Capitalized in a Title?

Whether you should capitalize a word in a heading or title depends on several factors, for example, its length. The position of the word is also relevant (specifically, if it’s the first or last word of the title). The most important factor however is the word class: Only certain word classes are not capitalized: articles, prepositions, and conjunctions. All other word classes (nouns, pronouns, adjectives, adverbs, and verbs) are capitalized.
Their is an adjective, a possessive adjective to be exact, just like my, your, his, her, it, and our. As a consequence, their must always be capitalized in title case, as illustrated by the following examples:
A League of Their Own
Stars in Their Eyes
Ahead of Their Time
