Ward's great-great-grandfather Welcome Potter had in 1785 married a certain "Ann Tillinghast, daughter to Mrs. Eliza, daughter to Captain James Tillinghast," of whose paternity the family had preserved no trace. Late in 1918, whilst examining a volume of original town records in manuscript, the young genealogist encountered an entry describing a legal change of name, by which in 1772 a Mrs. Eliza Curwen, widow of Joseph Curwen, resumed, along with her seven-year-old daughter Ann, her maiden name of Tillinghast; on the ground "that her Husband's name was become a publick Reproach by Reason of what was knowne after his Decease; the which confirming an antient common Rumour, tho' not to be credited by a loyall Wife till so proven as to be wholely past Doubting." This entry came to light upon the accidental separation of two leaves which had been carefully pasted together and treated as one by a laboured revision of the page numbers.
