Thank you Beth. I was aware of the obit, but forgot about Martha being named in it,thank you. However Martha may have been visiting her son's house at the time of his illness and death.
I'm now wondering if the 1922 date is a date of death at all?
The odd thing also is, Martha did live with Mary Decker for some time and there's no trace of death for Mary Decker either. I find that very very odd, even though i'm sure they are not connected.
I do know, Martha had died by 1924,from the will of her Niece
Thank you Beth for searching.
