old family stories start in various ways.My great aunt, whose name was Rebecca and whose father (born in the American backwoods in 1850)was named Isaac, once commented that "we must be Jewish." I heard this repeated many years later, told with amusement. Others may have taken it seriously. If so, they could have started observing some rules from Deutronomy or even copied from practices from Jewish neighbors.
