Thanks for the census records. Do you show the birthplace of the parents for this same group?If I understand the information provided (and read between the lines) then.
W. (1792-___) and Elizabeth (1795-___) Brown were born in New Jersey.They had at least the following children:Abraham (1817-___), Barclay (1822-___), Eliza (1823-___) and Rebecca (1824-___).All the Brown children were born Ohio.Eliza married a Miller and Rebecca married a Black.
Eliza (Brown) Miller was widowed by 1860 census but not before they had at least three children: William (1850-___), Julia Ann (1853-___) and James L. (1856-___).
Based on this information I should be able to find a marriage in Butler County for an Eliza Brown and ____ Miller sometime between 1843 and 1850.
Just for general information, I found a James L. Miller in the Middletown Directory for 1910 with a wife (Nannie) and in the 1912-1918 Directory with wife (Juanita).In 1910 he was listed as a teamster for F.M. Kemp.In 1912 he was a laborer for the Manchester Machine Company.There was a Charles Miller who was a Superindent at M. Machine Co. at the same time born about 1864.By 1914, James was a tool keeper for M. Machine Co. and by 1916 he had moved on to the American Rolling Mill Company where he remained through 1918.That's as far as I have looked in the Directories.
