Hello Ron.
Thank you for this valuable information. I found a James Grooms and John Grooms adopted by a John and Bridget Garret in the 1911 Canada Census. Do you have any theories on this. Eva Walsh is on a 1910 USA census (she is widowed by this time) listed with her daughter Mary, her mother Ellen (also widowed) and another son Harry but not James and John.
John Richard Groom is my grandfather and I do remember relatives saying he and his brother were orphans. It is confusing why Eva would be in Boston with only two of her four children.
