I am looking for information about my grandfather, JOHN MOLIERE LUCAS. He was a dentist in Lincoln for many years. The 1900 Nebraska census lists him with a wife, LURA, and 4 children-(Rich, Milton, Pearl, and Caroline)--the eldest was my father, Rich, who was about 8. They moved from Lincoln about 1903 and came to Missouri. In the 1910 Missouri census, was listed only the son, Rich. I have looked everywhere but fail to find a trace of the 3 younger children. Where should I look now??? Lorene
