I am researching Marvel family. William E, b1812,m Catherine Laws; James b1781, m Margaret. Later, Alfred S., b1848, m Amanda Sullivan, b1850. These folks lived in Dagsboro Hundred and moved to Seaford after William's death, 1859.
I have been to Dover Archives and have charts on many Marvels, but cannot make my family's connection during early 1850's. Maybe someone can make the connection!
