I have found no paper record. All I know of my 5G-grandmother is DNA evidence from one of her direct matrilineal descendants. In view of Captain Toney's standing among the Mi'kmaq, I initially assumed he might have married a Mi'kmaq; but the DNA evidence does not support this. The direct matrilineal descendant of Captain Toney and his wife has mitochondrial haplogroup M1b1, thought to have originated with the African people of Timbuktu. The haplogroup is today relatively common among people of Spain and Portugal, suggesting it may be a remainder of the Moorish occupation of the Iberian Peninsula more than a thousand years ago.
Since most early intermarriage was between European men and Mi'kmaq women, Metis mitochondrial DNA of the era was predominantly First Nations' haplogroups A, B, or C. It seems more likely Captain Toney's wife was descended from a Portuguese fishing family. Although I did not inherit her mitochondrial DNA, I inherited a segment of her DNA in chromosome 3 which has been identified as sub-Saharan African.
