Where in the World is Huldah Rowley Fenn?

I believe Huldah Rowley, my paternal third great grandmother, is the daughter of Hopkins Rowley and Elizabeth Stuart (Stewart), but of course, I do not have definitive proof of this.

Huldah Rowley married Daniel Fenn in Shoreham, Addison, Vermont.  They were the parents of nine children, Orpah, Tully C.P., Betsy, Aminda, Orlo H, Daniel C, Abel, and 2 unnamed. Daniel and Huldah were settlers in the Michigan Territory, arriving in 1833.

I haven't been able to find Daniel and Huldah in the 1810 Census and believe they may have been living with her father, Hopkins Rowley, in Shoreham, Addison, Vermont.  The ages of Daniel's family and Hopkin's family match for that census, but since no names are recorded I can't be sure.
