Place of birth is from a photo of Pearl as a tiny baby with Mother Father and sister Ruth: notes date of 1907 and Ruth is 5 1/2 Years old. From the photo and the dates given she would be born in 1906 at at the earliest.

I believe Pearl, 2nd, married a Mr. Wineberg.

In the 1920 Census:
Boarder with James Caley
45(8 or 3) Sanchez St.

Gives her age as 15. means she was born in 1904. and born in California and maybe San Francisco.

Ruth and Pearl were separated when Ruth went to San Juan to live on the Ranch with Grandma Bingham. They later located each other somehow probably when Ruth moved to Alameda as a young woman. Pearl’s name would have been Ollom and she was living in San Francisco in 1920 when Ruth was in Alameda with the Nelsons.
