The original requester obtained the words she wanted, but there is another song by the same title:

A CHILD OF THE KING (1877) Key: F
Words: Harriet E Buell Music: John B Sumner
Harriett Buell wrote the words for A Child of the King one Sunday morning while walking home from her Methodist church service. She sent her text to the Northern Christian Advocate, and it was printed in the February 1, 1877 issue.
1. My Father is rich in houses and lands,
He holdeth the wealth of the world in His hands!
Of rubies and diamonds, of silver and gold.
His coffers are full, He has riches untold.
CHORUS
I'm a child of the King! A child of the King!
With Jesus my Savior, I'm a child of the King!
2. My Father's own Son, the Savior of men,
Once wandered o'er earth as the poorest of them;
But now He is reigning forever on high,
And will give me a home in heav'n by and by.
3. I once was an outcast, stranger on earth,
A sinner by choice, an alien by birth!
But I've been adopted, my name's written down,
An heir to a mansion, a robe, and a crown!
4. A tent or a cottage, why should I care?
They're building a palace for me over there!
Though exiled from home, yet still I may sing;
All glory to God, I'm a child of the King!
