tigajess on Family Tree Circles

I need some help with a search if anyone has some time to spare! Looking for a death of Marcia Ruth Bussell maiden name Corbin in Dorset, England, I have her in the 1891 census but her husband died in 1898 and by 1901 census her youngest child was found in the District Royal Seamen and Marine Orphan School...I'd love to find what happened to her? I've tried Ancestry searches but have found nothing.
