Here is the full quilt, very large 104" x 108" with a variety of signatures/names from Philadelphia, PA and several Welsh Quaker towns like Tredyffrin, Gwynedd, also Bristol, Bucks Co, Montgomery etc. Some of the surnames are Green, Simmers, Foulke, Lukens, Jones, Downing, Huffnagle. Based on the towns and surnames and also a Quaker style dating method, I believe this is a Quaker quilt.
And here is the fabulous highly glazed cotton chintz backing fabric
And here's the block for CE Green: a grape vine branch. A number of blocks also have Green surnames.
Please let me know if you have any questions or have any information to add.
