10 years ago you posted your message about Oetjens from Helvesiek & Ostervesede, and the offer of names and dates for anyone with ancestors from those locations. Its a long shot but perhaps you may have a link to my Etjens/Oetjens
I have come across an "Etjen" in my family tree but know very little about him> What we know is as follows:
John Etjen, Stone Cutter (carver of gravestones), married to Eliza. Lived in the parish of St. Georges in the East, London, England (now part of Stepney/Poplar/Whitechaple in Towerhamletts). Burial 21 July 1847 age 88 (inferred date of birth 1759). Had 4 children Mary Ann (b.1794),Louisa sarah (b. 1797) - my ancestor, Maria Sophia & William Wise (b.1800).
