So sorry I haven't responded sooner---VERY busy.
Johanna Reed Engberg is my Grandfathers Aunt.
Anna Engberg was m. to E.(Ed) Olson (my Grandmother's brother)son of P. Adolph Olson.
I have NOT heard of an Arvid---but have many unidentified old family pics taken in Chicago.
I'm not sure which Charles or Gustaf you MAY be talking about. Web have many.
