Frank P. Harvey (1878-1958) married Hattie Belle Weatherwax (1887-1942). Today while verifying Michigan death records  I discovered they had an infant son Maxwell Frank Harvey b:6 Jul 1921 in Waverly,Van Buren co MI. Died 8 Jul 1921 and buried in Robinson Cemetery Gobles,Van Buren co MI. This son does not appear on any USC record you must use MI death records to find him. When I went to Find A Grave there was no maker for this son. His parents are there in Robinson Cemetery  Van Buren co MI, but not indication of this son. So if you are researching this HARVEY line or the line of her parents: Clement S. Weatherwax (1862-1952) and Jessie M. Boothby (1862-1941) you need to check the websites: (seekingmichigan.com) and (Findagrave.com)
