1867: Where Was Emma?

It's nice that I am still getting thrown as I wade through newspapers, looking for bits of Emma.

The conventional chronology (including mine own) has Emma in England continuously from the fall of 1865 to the fall of 1869, when she supposedly returns to the US to arrange for publication of Modern American Spiritualism (in 1870). On this trip, she is alleged to have met William Britten, making sense of the marriage in 1870. (I am fairly certain she knew William much earlier than that).

What to do then, with this announcement on the front page of the New York Herald for January 26, 1867?

Mrs. now. She left the US, in 1865, as Miss.

Or how about this one, from the Cincinnati Daily Enquirer for May 22 1867?

If these lectures actually took place, that places in Emma in the US for at least the first half of 1867.
