Trying to source birth or baptism record of Mary E. Brush (Brush-1348) daughter of Stephen Norris Brush (Brush-1102) and Mary D. Smith (Smith-254215) to determine Mary E.'s probable birth year.
The book " The descendants of Thomas and Richard Brush of Huntington, Long Island, Gateway Press, Baltimore, Maryland, 1982. P. 229.
https://www.familysearch.org/library/books/viewer/184782/?offset=0#page=231&viewer=picture&o=download&n=0&q= Image 231" lists Mary E. Brush birth year as 1845, however the 1850 US Census lists her age as 12 indicating she would have been born in 1838.
I found information on Stephen Norris Brush and Mary D, Smith's marriage and have confirmed their marriage year of 1845. See Early settlers of New York state : their ancestors and descendants - v. 8, no. 7, 8 (January 1942) p. 298,
https://www.familysearch.org/library/books/viewer/456714/?offset=0#page=10&viewer=picture&o=info&n=0&q=. It seems unlikely they would have had Mary E. 7 years before they were married.
Mary E.'s birth/baptism record is important to determine which of the two Mary E. Brush married George Wallace Downs - Brush-1348 or Brush-1099.
I suspect Brush-1099, but that Mary E. has an issue with birth state as listed in various US Census records.
Any help in sourcing record is appreciated.
