Hello KMG1124. I began this thread. George Walker's sister, Isabella was married to my husband's great grandfather Duncan Walker (unrelated families). Isabella and Duncan Walker had 4 sons, John , Archibald, George, and Alexander. Alexander was my husband's grandfather. He married Agnes Jardine and they had 5 sons, Duncan, James, Alexander, George and Robert. I am happy to let you have more information but it should be by personal message and in order to do that you must write two more posts. Hope to hear from you. isk.
