My brother-in-law's surname is Deyerling and his grandmother was Anna Pendl, who Married Benedict Deyerling.
Anna's father was Emanuel Pendl and her Grandfather was John or Joanne Pendl and grandmother Mary E Gerold. I have placed all the information I have found so far on Find A Grave with the tombstone pictures. According to the Deyerling Family, John Pendl carved the altar at St. Joseph's Church on Hill St., South Bend, Indiana. That church was rebuilt. Also, I have The 1880 Census of St. Joseph church that lists the Pendl's: John Pendl 60, his wife Mary Gerold age 42, Children: Mary, Emanuel, Franz, Andrew, Peter and Johannes.
I have all the obituaries and marriage records. I can send any that you would like to you. Patrick Warford
