From Connie Rickman:

It is believed that Nicholas,Sr. emigrated form Germany prior to the Revolutionary War.( Others
researching this family believe he was born in Lancaster Co., Pa.) The Fayette, Somerset and Berks
Co., Pa. Mossers' are believed to be descended from Nicholas, Sr. or his brothers.

The name is spelled on various sources as Mosser/Musser/Masser/Moser etc.

The Mossers were Brethen (also known in America as Dunkers and Baptists) of German origin.

After the War of 1812, Nicholas, Sr.  moved from Lancaster Co., Pa. to Selbysport in Garrett Co.
Md.  His sons Christian, John and Nicholas accompanied him.

Nicholas V. Mosser is believed to be buried on his 200 acre farm in Selbysport. He purchased the
200acres from John Simpkins in 1804 ( Land deeds from Allegheny Co. Courthouse, Cumberland, Md.)
