Just heard that Ancestry is offering free access to immigration records this coming weekend (Thursday, 3/14, through Sunday, 3/17). This may be a great time to take advantage of their resources. I will be digging for info on my Sargents (aka Slaymakers), and I’ll see if there is anything else to glean about my Trewins.
Update 3/14: I’ve been on Ancestry to check out the “free” access weekend. Once you find a “carrot” that looks promising and click on it to find out more, you are shown a window to sign up for a free 14-day trial. I guess it’s still worth doing, but the free trial is available 365/year anyway.
