The older Samuel Feast was the one who bred the rose you mention. He did have a son named John and one named Samuel. This branch of the family wound up moving out to Colorado. The John Feast you mention with Sarah and children, i.e. Loudon, Linnaeus, Edward, John, Dilwyn, Elizabeth - that is my gg grandmother's (Sarah Uppercue) 2nd husband. Edward is my great grandfather. I know that this John was the older Samuel Feast's brother. John Feast was also a florist and dealt in exotic flowers (esp orchids). Samuel Feast had a flower business for 100 years in Baltimore. John's did not last as long. From John's flower business sprang Kirkley florist. I actually worked there as a teenager. Let me know if there is anything else I can help you with.
