I have photos and info on the Greenlands on the website titled :"Old Family Photos". The address: www.oldfamilyphotos.com
You can either type in the name "Greenland" in the box that asks, "Who are you looking for?", or you can go to the section on "Huntingdon County, PA".
I am a great-great-great granddaughter of Caleb Greenland and Christina Curfman Greenland. My great-great grandmother was Missouri Greenland Brown. My great-grandmother was Minnie Brown Harclerode. Minnie's husband, Samuel Francis Harclerode is related to the brothers who married Sarah Ann Greenland and Rachel Greenland (Missouri's sisters). So, I am doubly related to the Greenlands!
I also have two photos of the Greenland Family Reunion of 1923 on the website. Perhaps you may be able to identify some of the unknown people?
Please check out all of my photos on the website I just mentioned! Perhaps you may want to submit some of your own photos to the website?! Please reply back.
