AZKATE1 on Family Tree Circles

Need information about ROBERT PARKER ROBERTS. He's the middle son of Robert Jeffries Roberts and Sarah Ann Sherman. Born in 1877 in BostonSuffolk Massachusetts, and died 1926 in Tasmania South Pacific Islands. He received a Mining Engineering Degree from MIT. Married to Cathrine Hubbard. They had 3 children and moved to Tasmania.

When Robert died, Cathrine moved back to the Roberts family place on Cape Cod, MA where she was not received well by Shermon Roberts, son of William Fredrick Roberts. She then moved out of the home and I have no more information about her, or her children.

Can anyone help???

Many, many thanks!
