I am also a descendent of William Albin and Martha Walker, through their daughter Mary A. Albin who married Samuel Burns. I have not been able to find to many people researching the Albins from Pa., I would love to exchange info with you!! I only have five children for John and Jane. I noticed that another posting asked about a daughter Sarah who married a Coleman. She is John and Jane's daughter. She married Samuel Coleman and around 1855-56 her and her family along with my line ( Mary and Samuel Burns) moved to Victoria, Knox County, Illinois. I also have some pictures that were taken right before William and Martha passed away.She sent the photos to my 4th great grandmother (Mary), it is an original, and has Martha's handwriting on the back.I also have a picture of John and Nancy Albin ( I believe John is Mary's brother and Nancy is her sister-in-law.) These photo's were taken in the same time period and all were taken in Mercer Co., Pennsylvania.
