My maternal grandmother was Minnie Sibbits (different spellings on different documents). Her father was William Sibbitts who had a twin brother named John. They were born in the 1850s and served in the Union army as teens before going West. We know his folks were from PA area. His mother was Mary, Mary Anne ? and she remarried and had a third son who was raised after her death by her sister. I thought growing up that the Sibbetts was Welsh. My aunt recently said English.

Any information is appreciated.
