Connie, I am a Ruckle descendant and the Ruckle/Ruckel/Ruttle line has been traced back to Casper Ruckel born 1660 in Germany... Your ancestor Margrath Ruckel Embury and my ancestor Sebastian Ruckel were brother and sister...their father's name was Casper Ruckel.. The house in Ireland where Sebastian Ruckel migrated with his father Casper Ruckel and their families is still standing and still lived in by Ruttles.(the Irish spelling).. The Embury's lived within sight of the Ruckels in Limerick..The Embury homeplace is in ruins...but there is a nice plaque on the grounds... I am in the process of looking for a needle in a haystack in the German Church records.."Casper Ruckel"...I have spent the last year searching and hopefully someday he will be found... My line goes from Casper Ruckel, Sebastian Ruckel, John Ruckle, Thomas Ruckle, William Hogarth Ruckle, Thomas Jefferson Ruckle, George Lee Ruckle, Homer Clay Ruckle, Everett Britton Ruckle, to myself Carole Elaine Ruckle Richardson. My Ruckle line migrated to Baltimore, Maryland in the early 1790's from Ireland...at least that is the first trace we found of them in Maryland...I still live in Baltimore, Maryland.... I have other info to share if you are interested in Ruckle history, but I don't know much about the Dulmage line... Carole
