I believe I am the original source of the grimshaw / boston / born at sea / seven sisters info
I started doing family history in about 1973 and was given the following verbal account by my Uncle, Albert(o) Barclay. This info then became accessible to others through www.familysearch.org
Albert told me that my ggfather Phillip Grimshaw was born at sea in about 1840 aboard a ship The Seven Sisters. He said that either the ship or the birth was registered in Boston. (He didnt know which - recent internet searches for info on The Seven Sisters indicate that it may have shuttled between UK and Pictau USA /Canada). According to my Unlce Albert His father James was the master of the ship. Phillip had a twin brother who joined the US Navy and died of a flogging (possibly around or after 1860) and was buried at St Helena. I believe that Phillip was ptobably on the same ship as his brother and the story is that at the first opportunity he jumped ship and returned to Scotland. Because he was wanted for disertion he had to change his name to Fraser, which was his mothers maiden name. His mother Eliza Fraser apparently came from Dundee Scotland.
Uncle Albert told me that Philip remembered his grandfather climbing vines at a place called Lower Falls in USA / Canada. I do not know how reiable any of the above information is but I have been trying to check it out ever since.
The 1920 US census shows Grimshaws living in Windsor County Vermont. There is a a place called Upper Falls near to the town of Windsor and there is also a place called Lower Falls which is some distance away, possibly in another county in Vermont. Pictau is to the north east of this region, near a place called New Glasgow
