Føly, Foley, Folie

Trying to determine where the last name "Føly" came from. Was it a farm or city name? Traced my ancestors to being on the Bark Juno in 1844 (arrival in NY June 24). Was this a direct trip from Bergen? Strange that the Brig Albion also left Bergen on that day arriving in NY on July 10th. Would they have attempted to be sailing together -- if they were trying to be together they obviously failed.) /emigration/passengers/?journey=956 (Bark Juno Passenger List) They are: ID 3238345 John Nilsen Føly 24 m ID 3238446 Johanne Føly* 24 f ID 3238547 Marthe Johnsdatter* Føly* 9mo f ID 3238648 Siver Elingsen Føly* 20 m ID 3238749 Lars Olsen Hove 23 m ID 3238850 Sigrei Nilsdatter* Milang 21 f They arrive in NY, then disappear from any records I can find until John & Johanne Foley show up in the 1865 Illinois Census - Their daughter Marthe apparently dead at this time (no record)? But four young children ages 0-11. An interesting part of the story is that John dies within a year or two of this census (family history says the "black death" or is it the "black plague") during a trip to Chicago. -- Then Lars Olsen Hove suddenly reappears from nowhere and marries Johanne (no official marriage record I can find). Lars takes the last name of Foley and they move to Minnesota. I'm trying to find any information on this group before their journey from Norway in 1844 -- and then the events after their arrival in NY. (I'm guessing they took the Erie Canal journey and wound up near Milwaukee or Chicago.) And, are John Nilsen Føly and Siver Elingsen Føly related? Do their "middle" names indicate different parents? Cousins? Not related at all? I can find no records of: ID 3238648 Siver Elingsen Føly* 20 m ID 3238850 Sigrei Nilsdatter* Milang 21 f after they arrive in NY? It appears that Sigrei was a traveling companion only by virtue of being listed next to them on the arrival list. Spelling can appear as Føly, Foly, Foley, Foli, Folie Sorry, lots of questions. Any answers are much appreciated. Archer
