Not sure whether you have found the following info: Isaac Myers death/burial in New Haven 1917 in Evergreen Cemetery (www.evergreencem.org
). You can contact the cemetery via email-form on their website & they will attempt to provide you with whatever info they have on file. The fact that the family has used two diff cemeteries was probably due to finances & availability of plots at the time of death. Isaac's widow Jennie was listed in 1940 census living with her married daughter Jennie Mahoney. An ancestry hint shows a public family tree named Genealogy that includes Isaac & Jennie as well as their children and Isaac's father Jakob. The member-owner believes that Jakob was a Civil War vet & died & buried in New Jersey. Based upon Jakob's age & his sons being born betw 1851 & 1861 it is most likely that Jakob did serve in the War.
Hope that this helps
