Hello! Likewise, two of my great great grandparents on my fathers side were from Amsterdam, immigrated to Spitalfields in England and then to Cambridge, Massachusetts!
If you see any artifacts, i.e., cigar boxes with "Phineas Fonseca" on them, please let me know! Also, the Busnach family is another of my family names of Dutch jewish cigar makers... Thank you!
