Their son Stuart was very talented and wrote poetry, songs, and stories of family and friends. The following was a poem he wrote about his parents:

Mother and Dad
Michael Dan married MARY Ann in a little town called Lilly
After moving around they settled down on a spot that was quite hilly
They built a home and cleared some ground
Added more to it, as each spring came around
They had ten children, as husband and wife
All are recorded in the Book of Life
After years of hard work, God took them away
But in each of us, he left a little replay.
