I have a George Albert Simonson, b 9 Aug 1849 on Staten Island, son of James William Simonson & Catherine Butler. Siblings include; Emeline b 1833, Abraham b 1835, James b 1837, Frances "Fanny" b 1839, Joseph b 1840, John b 1843, Catherine b 1844 & Gitty Ann b 1846.
James' father was Abraham m to Susannah Wood.
I don't have any census or other records for most of the lineages I have at this time, but work on it occasionally, since college has been taking up my free time. Hope this helps to get you on your way though. :)
Would appreciate you 'filling in the blanks' for me on George, with what you've found.
