I came across your post while researching Beyren Luxembourg. I am also a Beckius decendent, I have slightly different information on Jean Beckius husband of Anne Liesch. (Jeane Wilhelm Beckius)
Their daughter Catherine Born 29 AUG 1781 in Kapenacker, Grevenmacher, Grevenmacher, Luxembourg married Carl Bisdorf, and their daughter Margaret Bisdorf born 27 Mar 1811 in Beyren, Grevenmacher, Grevenmacher, Luxembourg married Nicholas Wagener. Their son Peter Wagner emigrated to Chicago, Ill, and later to North Dakota. He was my great Grandfather.
I visited Beyren last fall and photographed the village, church and cemetary. I did take photos of the Beckius tombstones in the cemetary.
Does anyone have all the family of Jean Beckius and Anne Liesch enumerated? Thanks John
