Allen TRULL II and Milea "Millie" Price TRULL
Allen Trull II was born in about 1804 in North Carolina, and died Sept. 16, 1847, in Union Co., NC. He married Millie Price, whose name I have also seen written as Milea, Mary, Milly, and Molly on various records. She was born in about 1804 in North Carolina as well. I'm unsure of when she passed away, but I cannot find any records for her past 1860, so I suspect that she died in that decade. Allen and Millie had 7 known children: William, Rebecca "Becky", Mary "Polly", Francis Marion, Andrew "Andy" G., Charles "Charlie" Evans, and Laura E.
Rebecca, Mary, and Francis were all born blind according to census records, and as such I have seen this branch of the family referred to as the "Blind Trulls." I have seen Francis in particular often referred to as "Blind Trull" in newspaper articles.

Pictured above are comments from the now-retired Genealogy.com forums, left by a Charles Trull claiming to be a great great grandson of Francis M. Trull, son of Charles E. and Rhoda Helms Trull. This info is unsourced of course, but it seems to corroborate that there were two Allen Trulls that were father and son, and that Allen Trull I and Solomon Trull were brothers. Charles does have accurate info on Francis Marion and Hester Trull as well. I would be interested in what further info Charles has on our family, but sadly I haven't been able to get in touch with him.
Probate records, Allen Trull II's will, marriage records, and a family bible establish Millie Price as the wife of Allen Trull II:

Census records show Millie as head of household, still living together with all of her children in 1850 - Allen II had passed away 3 years prior. In 1860, Millie is still the head of household, and living with children Mary, Francis M., and Rebecca.

Daughter Rebecca was recorded as being 26 years old in 1850, and this census also states that she was blind. However, presumably the same Rebecca on the 1860 census was not noted to be blind, and was said to be 21 years old. I also noticed that daughter Mary was not noted as blind in the 1850 census, but the 1860 census states that she was born blind.
