Just spoken with my grandmother. She does not have any paper records and does not know what has happened to them. However, she is planning to visit Morton's living child in September who will very likely remember as they know all about the family. She also mentioned that Morton and Sarah eloped, which wasn't revealed until 1970. But I may have to update this thread in September: just wanted to see if there were any leads which I may have missed. The censuses look to be a fantastic start. Thank you so much!
