According to FamilySearch.org this is Lewis Post Vanliew, son of Ethanon Vanliew and Eliza Wood of Seneca Co NY.
Lewis/Louis was carpenter. He appears in the 1850 & 1860 Seneca censuses with his parents, then the 1870 Cayuga census with a Groome family, and then in the 1880 Cayuga census with wife and child. (Lots of creative spelling of the names, but he is there.)
I found them in Blair, Washington Co NE in 1900 as L P & J E VANLORE with 3 children, Maud b Dec 1880 NY, May b Nov 1882 NE, and Ross b Jun 1884 NE.
In 1910 they are in Blair as Louis P & Jennie VANLON with only daughter Maude B.

This is not my family - I am researching John Vanliew, son of Daniel & Caroline Vanliew of Cayuga Co NY, for a friend. I suspect Daniel and Ethanon might be brothers.
