Every family has a story, and often those stories are passed down from generation to generation. But what happens when a family?s story is not passed down? This proved to be the case with Jessica Biel, who recently uncovered a missing element to her Biel line?s story. Jessica grew up without knowing much about her Biel line. She had been told that the family was German, but no further details were passed down to her. What she found proved to be pretty astonishing. When Jessica began her journey, she started the way genealogists often do, with census records. From the 1910 U.S. census, she learned that her great-great-grandfather Morris Biel worked as a cloak cutter, was born in Austria, and spoke Hungarian. Not only did this show that her Biel family might not be German, it also hinted at a possible Jewish background: Morris is a common Jewish given name, and cloak cutting was a very common profession for Jewish immigrants at that time. When something like this crops up in your family tree, one of the best places to turn can be one of the least expected: a DNA test. Jessica took a DNA test through AncestryDNA, which calculated that her ethnic breakdown included 8% European Jewish DNA. While this DNA test doesn?t indicate which line her Jewish ancestry came from, it indicated that it was a part of her background, and continued research into the Biel family revealed that they were Austro-Hungarian Jews that lived in the town of Zsolna (in modern-day Slovakia). DNA tests can tell us some pretty unexpected things about our heritage. One of the best things to do with your DNA results is use them in conjunction with available records to build out your family?s story.
