Thanks for the info on Thomas Eagar - He is a distant ancestor, but it's still good to know that he wasn't in Sing Sing as a convict.
My information varies somewhat concerning John Eagar, son of Thomas and Lucy Buell. John did come on the Brooklyn. His name is on the list of people that booked passage on the ship as published in the Times and Seasons newspaper published by the Mormons in New York that chartered the ship. You can see a copy of it at http://www.shipbrooklyn.org/ISRAEL.html
. He later recounted the journey in a letter in which he describes seeing icebergs as they passed around the cape. Look at http://www.indirect.com/www/crocket/brookly.html
for excerpts from John's notes. He became assistant editor at San Francisco's first newspaper and actually owned property in San Francisco.
John was the only member of his family that stayed with the Mormon church - all of them appeared to join the church in New York - that's why they took the ship - it was chartered to take a group of Mormons out west.
John went to Salt Lake in '47 or '48 and married Sariah Anna Johnson. If you have information regarding an earlier family of his in New York, I would be interested to know about it.
I have been able to put together a bit of information about John's family and descendents and I have Eagar pedigree information going back to Alexander b. about 1635 and his father Robert, but I don't have much historical information beyond names and dates before John. I'd love to find more - I enjoy putting stories to names. The prison info sounds interesting, I'll e-mail you about it.
