No problem, here's a link to the use of the singular they in Jane Austen's novels:

One of the examples from Pride and Prejudice:
"To be sure, you knew no actual good of me -- but nobody thinks of that when they fall in love."
Shakespeare did it too:

A Comedy of Errors, Act IV, Scene 3:
There's not a man I meet but doth salute me
As if I were their well-acquainted friend
And the King James Bible does as well:

Singular "they" appears with the antecedent "his brother" in some versions of Matt. 18:35:
So lyke wyse shall my hevenly father do vnto you except ye forgeve with youre hertes eache one to his brother their treaspases. (Tyndale, 1526)
So lykewyse, shall my heauenly father do also vnto you, yf ye from your heartes, forgeue not, euery one his brother, their trespasses. (Bishops, 1568)
So likewise shall mine heauenly Father doe vnto you, except ye forgiue from your hearts, eche one to his brother their trespasses. (Geneva, 1587)
So likewise shall my heauenly Father doe also vnto you, if yee from your hearts forgiue not euery one his brother their trespasses. (KJV, 1611)
