Maybe you can help me with my information on Cuyler and his background. What I have does not exactly fit your info and since it is your family I figure you must have more correct info. What I have is
Cuyler Campbell Supplee (2/13/1894 - 5/3/1944 Los Angeles) married Maude Wiggins Anders in 1917 in Philadelphia I also have other marriages for him Esther Ritter and someone named Adrienne or Adeline C. Cuyler and Maude had the two children you mentioned, plus a child from a marriage Maude had with a George Mehl
I have Cuyler's father as - Cuyler Supplee (1874 - ) who married Frances Barrett (3/1875 - 7/25-1960) their children were Cuyler, Leona Stahl Supplee 4/1900 - 7/21/1901), and Francis Barrett Supplee (9/10/1901 - 10/1984)
I have Cuyler's grandfather as - Warren Supplee (5/1838 - bef. 10/1918) who married Anna Center (4/1842 - ) about 1865 their children were John H, Warren C, Anna, Cuyler, Walter Brooke, and Henry W
I would appreciate any help you can provide to correct what may be my misinformation.
