Thank you very much for your quick reply. William left two known children, Francis M. Johnson and James Johnson, both living with their grandfather Nehemiah Johnson in 1870 Lafayette Co., AR. Another son from his second marriage in 1860 was John M. Johnson, born in 1861. His mother was Nancy Wyatt Hurst. They were alive in 1870 Dallas Co., AR. Nothing is known of what became of these children.
