Possibly the same child as Lizzie. She appears as Golda age 13 in the 1920 census, but there is no match for her in the 1910 census unless she is the same as Lizzie (who appeared as age 5 in 1910, and does not appear in the 1920 census.) On the other hand, the 1910 census recorded Emeline as the mother of 6 living children, and there were only 5 in the household, so Golda may have been accidentally skipped. And Lizzie might have been married by 1920.
