I believe that Ira, Calnetta (Calnettie), Salina (Lena) and Rachel S. Roy are children of Laura (Lenora) Roy. I don't think Laura was married. Laura was born in 1870 and died in 1898.

Laura Roy:

20 Apr 1870 birth, Tucker bk1 p25
Lenora Roy, parents Simeon K & Sydna Roy

Apr 1898 death, Tucker Co bk1 p101
Laura L. Roy, parents Simon & Sydney Roy
age 28 yr., birth date 2 Jun 1870

Ira's father may be George Kline. Here is the obit for Ira:
