I have never been able to place this Lewis W. Griswold within the proper family but the Toledo OH Death Index shows that he d. 21 Nov 1895; 68y. Other records on him that we have state he went to Toledo about 1879. And a daughter, Eva Marie Griswold b. 1854 in CT. So it would seem that he should be in the 1860 census of CT but perhaps you have all ready checked that? If you have other information on Lewis, that might help place him with his parents that would be much appreciated.
