In April 1858, when Henry was just 3 months old, after his mother and twin sister died at his birth, the call came for all Saints to leave their homes in northern Utah, and journey southward. His father, Simeon Adams Dunn loaded a few provisions and household effects into his covered wagon, assisted his motherless children to their place in the wagon box, and cracking his long whip over the backs of his oxen, commenced his journey. He had also provided a wagon for his eldest daughter and her three little girls, and they traveled together. The husband and father of this little family, Martin Luther Ensign, at that time was serving as a missionary for the Church of Jesus Christ of Latter-day Saints.

As they proceeded on their way, baby Henry became very ill. They camped on Kay's Creek, (now Kaysville) and there they saw the life depart from their lovely three-months-old baby son and brother. The father made his little family as safe and comfortable as possible in this temporary camp, and with a sad and heavy heart slowly wended his way back to the lonely grave in the Brigham City Cemetery. Very near to it he dug a very small, new grave, and in it tenderly laid the remains of his baby boy.

He found the town empty, except for a few men who had remained behind, ready at a moment's notice to touch a match to the homes and buildings if the enemy should enter the city. He went into his house, expecting to spend the night there, but it was so quiet and lonely it was more than he could endure, so he went to the stable, laid down by his faithful oxen, and spent the night near them. Early the next morning he was on his way to rejoin his family. He found them safe and well and they continued their journey as far south as Payson, where they made their camp and remained until the Saints were counseled by the Church leader, to return to their homes.-- Eva Dunn Snow.
