I'm not sure what info you were able to get from jerry, but I can share what I have. I am the Great-Great Grandson of john Solomon, and this is what I have with regards to your question of location in 1840.
As the 1st of 3 children born while in Nauvoo was Ann Adelaide Fullmerb/25 Oct 1841, and the last child born in Tennessee (Murfreesboro) was Joanna Price Fullmer b/13 Dec 1839, My supposition is that they were in Tennessee until the Spring of 1841. This may or may not be of help to you, however, if I can be of any further assistance, pls do not hesitate to contact me.

Sincerely,
