Thank you for your response.
I am the son of "Leroy" McPherson, who for the rest of his life was known as Roy James McPherson. Evelyn (McPherson) Sauer was my aunt.
Since I posted this enquiry about 10 years ago, I have beem able to find our immigrating ancestor, John McPherson, who came thru New Orleans to Council Bluffs, Iowa, in 1851.
I am assuming we are related. If you would like any information that I have collected, please email me at firstname.lastname@example.org
