It seems plausible, though apparently not reported anywhere, and unsupported by any evidence, that Hannah may be Person:Hannah Heald (5), d/o Gerhsom Heald and Hannah Parlin. Source:Parlin, Frank Edson. Parlin Genealogy, the Descendants of Nicolas Parlin of Cambridge, Mass reports that said Hannah Heald married Moses How but lists that as her only marriage. Instead, it seems probable that the widow of Timothy Heald married Moses How, since she turned over her dower rights to her children days before the marriage to Moses. Now, it is not clear if the Parlin Genealogy was making a bad assumption that Moses How married an maiden, or if there is evidence that actually suggested he married the indicated Hannah Heald. But the age of Hannah Heald is appropriate to have married Timothy Heald, and other than Moses How, there seems to be no other marriage attributed to her that would rule out a marriage to Timothy. And of course, having both married and maiden name be Heald would tend to obscure a previous marriage.
