I have a complete history of John Maxwell (1850-1920) and Margaret Carswell 1850-1943) and the children including John Cleveland Maxwell ( 1885-1975) and photographs, census records,  etc. I can tell you about the family since I contacted Fred Maxwell (1932-2011+) of Mindenmines MO. I have the Maxwell story for prior generations also. Give me an address or phone number and I will communicate it to you. Or call me on 760 2092 4627, I live in Rancho Mirage CA. Bill Maxwell
