Keep in mind, 'You never know' and especially with unusual names. While in Maine doing research on ANDREWS, MANSFIELD and PEASLEY surnames, the genealogist told me to trust my gut feelings and copy anything that was remotely the same. ( Not knowing when I would get back her way).
She told me that the name used by Grandfather Luther "Dyer" ANDREWS was actually a surname in Maine. I looked up MANSFIELDS and PEASLEY's and far back early 1800's there always was mention of the twins Israel and Nathan PEASLEY. Seafaring men and their children. Never could tie our line to them, although it was an interesting read. I found one page mentioning their wives (LOOK family) who were sisters, and when one twin died and one sister died, they married the surviving spouse of their sibling. OK! Someone had to raise the children and living on an island!Happened a lot.
I kept looking at the LOOK family of several sisters that had married twin brothers and stopped. Another sister, Delano, had married a Luther DYER. Now a family I can not tie into, but on the same page are all the names I am looking for and an unusual name at that. Luther for a first name is not common. I do not think I have seen it anywhere else during the early 1800's. I copied the information and put it aside.
About two years later, I did in deed tie the families together. The twins (one of them) are direct descendant to my husband and obviously Uncle Luther DYER was a favorite and a niece, Lena PEASLEY ANDREWS named one of her sons, Luther DYER ANDREWS.
I agree that Isaac Newton METZ b. 1865 is very unusual. Of course not the Isaac, but Newton- unless named for the scientist and to show education was important. Another unusual name attributed to a sibling in this family is Jacob Rainier METZ b.1873. Remember this was just after the Civil War. Men as soldiers had travelled all over the country. Had Jacob METZ b. 1833 (Father to Isaac) been in Civil War (Union or Confederate)? Had he met a relative in Maryland? Or Jacob's wife, Sarah/Sally RABER b. 1837 tie into the family. Where did she come from? I did not list her parent's, but they are on the list as: Bill and Cassie Fluharty RABER. I am taking it that FLUHARTY was probably Cassie's maiden name.
Jacob METZ b. 1833, mother's name was Sarah FLETCHER b. 1809 in Greene County, PA. Her parents are listed as James and Rose Colgate FLETCHER. Again I think COLGATE was probably Rose's maiden name. No mention of where they are from. Andwatch for spelling errors or interpretation. (You probably know this).
I for several months had questioned why my great grandmother and young grandpa were listed as boarders on the 1920 Census in Ohio in the home of the SCHRANTZ family? With others help and my Mom telling me family names, we realized the divorce was in process and grt. grandma was living with her Aunt and Uncle SCWARTZ.Seems obvious now!
Good luck! I research for awhile, then stop and start again. Many have helped me with info. and leads to follow. If you find anything let me know.
I am still unclear if the METZ' are German or French nationality.Or when allegedly came over. Evidentally prior to Am. Revolution War according to this manuscript. I have heard some say Alsace Lorraine. I know from history that area seemed to have gone back and forth between Germany and France. I have LAMPE in my family and find the same problem of French or German. It is a true French word, but... Good luck again.
