Hair memorials whether made into jewelry, woven into wreaths and pictures, or small locks of hair sometimes placed in a locket, were a remembrance of loved ones or friends. We normally associate these memorials being made after someone was deceased, but they were also keepsakes of dear ones who might have moved away, including soldiers who were away fighting in war.

The Gatherings Antique Vintage  has several lovely framed examples of hair keepsakes in a collection. This one is signed Henrietta Livermore, June 1, 1813. The poem with the the woven lock of hair is very touching...

"Remember me when you away
Remember me at dawn of day
And when dear heart this you see
O then bestow a thought on me"

Possibly she had presented a woven lock of hair, as a love token, to someone that was going away. The locket of hair is pinned with a silk bow and attached to paper.   

Dated 1813
