Unfortunately nobody has found his parents yet in Geni, nor in MyHeritage. You might want to look around in ancestry.com if you have a subscription.
Hi Carson,
I am in the same boat. You have probably looked at my tree...I'm still working on it. My ggrandparents were Frank Olmstead and Mary House. Mary's mother's maiden name was Lucinda Green and she and Nancy both lived in Courtland County, NY. So this is another thing to sort out. Years ago, when FTDNA started doing Y testing, I tested my mother's Olmstead cousin. I wanted to see if our Olmsteds were related to the Olmsteds who arrived in Massachusetts in 1634(?) on the ship Lyon. I joined the Olmstead group and Laurance is grouped with the descendants of that group. Frederick Law Olmstead was also a descendant of the Lyon group. The census says Ebenezer was born in NY, but in those days NY and Connecticut had fluid borders...I looked there, too, but gave up. Let me know if I can work with you to find their past.
Try the spelling of it as Olmsted. I live outside of Harrisburg, PA area. Before it was called Harrisburg International Airport, it was called Olmsted Air Force Base.
From Wikipedia:
Robert Sanford Olmsted
The facility was named in honor of 1st Lieutenant Robert Sanford Olmsted, U.S. Army Air Service, on 11 March 1948. 1st Lieutenant Robert Sanford Olmsted was killed in a ballooning accident over the village Loosbroek, Netherlands on 23 September 1923 while competing in the Gordon Bennett Cup.[1][2][3] Olmsted remained in the race despite threatening weather which caused some competitors to drop out. Lightning struck the S-6 over Nistelrode, the Netherlands, killing Olmsted.[4
