FamilySearch.org may have better versions of passport photographs than Ancestry.com's database, so check it out. Sometimes these pictures are the only available images of a deceased relative.
In the example below, the image on the right is a passport photo of Eugene Totten Bishop from Ancestry. The application was signed in 1918. On the left is the same image from Family Search, revealing more detail.
|Eugene Totten Bishop (1876-1936) was my father's great granduncle.|
He was born in Newark, New Jersey to William Reuben Bishop and Susan Jane Marsh.
I have not found a marriage or children for him.
He died in Newark and is buried at Evergreen Cemetery in Hillside, New Jersey.
Eugene resembles a man in a Bishop photo album I acquired from eBay years ago. I do not know if this is my family or not.
