The second death notice of Mary Graves born Coakes says she left behind no issue. A letter in the estate lists her blood relative as her brother Harry Coakes (https://www.familysearch.org/ark:/61903/3:1:3Q9M-CS7P-R9CF-J). She would seem to be born from union of Samuel Peter Graves and his first wife Elizabeth Martha Graves (https://www.familysearch.org/ark:/61903/3:1:3Q9M-CS7P-R98X-L). A letter from him states that too (https://www.familysearch.org/ark:/61903/3:1:3Q9M-CS7P-R9CN-C).
