According to the Jeanette Scriver Burch book, "a document signed by Gilbert L. Schryver, dated 2 Apr 1858, of LaGrange, Dutchess Co., states he had been a Private in Henry Platt's Company in the Infantry in the War of 1812.  He had been drafted, could find no substitute, so served.  He was ill for a time before he was discharged at the end of his term in December, 1814, in New York city.  Many years later he received from the U.S. Government for that service 40 acres of land in Iowa and later a Land Warrant for 120 acres more.  He sold the bounty land to support himself in retirement.  His second wife, Sarah, had acquired land from her first husband, and Gilbert purchased more.  A number of other land records concern purchases and sales by Gilbert during his lifetime.  At his death Gilbert still owned 18 acres he had inherited from his second wife plus six other acres."

"In 1842, the Freedom Plains church complained about his poor attendance, and when he did not respond, he was excluded from the church for neglect of public worship and intemperance.  It seems that he stayed clear of the church for the rest of his life ... After Eliza's death, Albert was a boarder for awhile, then finally lived with his daughter, Lucetta, who had married John WOOLLEY.  Their family was living in Gilbert's old homestead.  He still owned some land at the time of his death, about 1867.

"His son Albert, who contested the small estate, purchased some of the land when it was put up for auction."

Gilbert's was married to Sally Cornwall on 20 December 1815, in the First Dutch Reformed Church of Poughkeepsie.  Sally ahd been born about 1799.  They had a son, William Henry, baptized there.  Sally died 28 April 1819, age about 20, at Manchesterville, NY.

Gilbert then married Sarah Van Voorhees Masten on 5 September 1822 in the Freedom Plains Presbyterian Church in Freedom, NY.  She was the widow of Daniel Masten and had been living there with him.  Gilbert and Sarah had two children, Albert and Lucetta in Freedom which was later renamed LaGrange.  Sarah was born ca 1795 in Beekman (probably what became LaGrange) and died ca 1831 in Beekman.

Gilbert's third marriage on 13 August 1833, was to Eliza Hagaman, the widow of John D. Hagaman of Pleasant Valley.  We have no other information on her.
