I'm starting to delve into my family's geneology. I do not have any info on my great-grandfather's branch at all. I only know his name is Francis (Frank) Thomas Casteel. He was married to Elizabeth Spear. They had an adoptive son (my grandfather Donald Franklin). They most likely lived in Garrett County, MD (or that region). He died on July 23, 1933. Any info on this branch that you can provide is very much appreciated!
