No, that's actually his second wife, Julia Luella Bynog.
Well, I'm not sure who Rose Lackey is but I know none of my family were from Maine....
Hmmm, that very well may be her! The date is the same and since the marker is supposed to be undreadable, it's possible they mistook March for May. Wow, thanks for finding this! I might have to go there and check it out myself. And if she's buried right next to Oscar then that would definitely make it right.
