Evelyn Louise McCarthy had two half siblings...Irene & John S. Irene I believe was born in Iowa (1891) and died around 1911. John was born around 1897 in what I believe was South Dakota. He lived into retirement but I have no date.
Also, I think maybe Emma's name was actually Imogene but they called her Emma.
Fred & Othelia were born in Germany...may have come to the US around 1880 and went to Iowa.
Can anyone confirm???
