1.  It is our family history that Ira Baker BROWN's parents were Willard & Mary BROWN.  The following is copied from papers handwritten in 1921 by Nellie (BROWN) KIRK, daughter of Ira Baker BROWN — and surely she would know the identity of her grandparents.  A typewritten copy was made from Nellie's hand-written original on 25 Sep 1941 by Nellie's daughter, Ida (KIRK) BAIRD.  A photcopy of the typewritten page was kindly sent to me by Nellie's GG-granddaughter, Kathleen HONTZ.  One of the items on the pages states:

Ira Baker Brown was born June 27, 1829, Birmingham, New York, son of Willard and Mary Brown.

Nellie erred about the location of Ira's birth (he was "of Birmingham, Ohio," at the time he married in 1853), but not the date, which we get, along with the correct location (Stockholm, St. Lawrence Co., NY) from Ira's military pension application.  The only question here is, which Willard and Mary BROWN?  Well, the only Willard BROWN in the 1830 census of Stockholm, St. Lawrence Co., NY, is our subject, whose wife just happens to be Mary.  Ira Baker BROWN left home before the 1850 census, enlisting in 1847 to fight in the Mexican War.  We do find Ira in the 1860 census of Hastings, Barry Co., MI.

Silas is Willard's ward, orphaned son of Nathan BROWN.  The other teen/pre-teen male is also too old to be the child of Willard or Mary.  Also in Stockholm:  Warren BROWN, Obadiah BROWN, and Samuel A. BROWN.

Nathan BROWN is newly married and also living in Castleton Twp.  Ira served in the Mexican War in 1847-1848, and when he married in 1853 in Detroit, MI, the license describes him as being "of Birmingham, OH" (n.b., there are four Birmingham's in Ohio, including one in Erie County).  The only likely Ira BROWN in the 1850 census is one in Erie Co., OH, though he's not in Birmingham.

Adelbert may be an orphaned grandson.  Listed next to son, Nathan BROWN.  I can't find Otis, Silas, or Alexander (or Delphie).  Son Ira BROWN is also in Hastings, listed five household from daughter Lucy BROWN, who is living with the NEWTON family (see next source).

Willard would only just be of age, himself (b. 1806/7).  So, is Silas his nephew or his younger brother?
