I know this is quite late in coming, but I just joined Roots Chat. I am researching an ancestor named Charlotte George, whose birthplace was Tryddyn, Flintshire, Wales. She emigrated to the U.S. aboard the William Stetson in 1855, leaving from Liverpool and landing at Castle Garden, NY. She is listed next to a family named Matthias, and in fact, on the Castle Garden website, is incorrectly listed by the name Charlotte Matthias, so I get the impression they may have been traveling as a group. For whatever reason, on the ship's passenger list, her name is sandwiched between the members of the Matthias family. I am wondering if they were friends or neighbors and thus traveling together. The Matthias family members include: Thomas, age 54, collier; Ann, 48, wife; Joseph, 24, collier; Hannah, 16, spinster; Thomas, 13, collier; and Edward, age 9. Their address is difficult to read but looks like "Lewis Davies...Jonathan Ellis...Brymbo...Wrecsam Denbigshire." My ancestor, Charlotte, was a convert to the Church of Jesus Christ of Latter-day Saints (LDS/Mormon), as were most others on board the William Stetson. Not sure if this is the family you're looking for, but it seems to line up pretty closely with what information you gave in your post. In that case, you'd be unlikely to find them in the 1861 Wales census or later since it appears they left for America.
