Her family is kind of a big deal! Katey Sagal is surprised to learn about her Amish heritage in the Sunday, April 17, episode of Who Do You Think You Are?, as seen in Us Weekly‘s exclusive sneak peek.
The TLC series’ preview clip shows the Sons of Anarchy alum taking a look at her family tree and discovering that one of her ancestors left Europe and was among the first members of the religious group to land in Pennsylvania in the 18th century.
When she hears that two of her relatives have last names that are considered prominent in the Amish community, the Married With Children actress quips, “I am seriously hierarchy Amish! Wow!”
A previously released scene showed Sagal’s shock over discovering her roots as she said with a laugh, “It seems I might be Amish!”
Watch her reaction to learning about her family in the video above.
Who Do You Think You Are? airs on TLC Sundays at 9 p.m. ET.
