Jim Jackson has given me permission to share this. It reminds me of the usefulenss of looking at the family  associated with the Quaker JACKSONs which includes a crest with two greyhounds and a dolphin. The family tree relating to this family is on the Rootsweb tree, (I update that tree fairly regularly) and also on this site at the page on the Quaker JACKSONs.

            A second account of Robert’s appearance on this continent came from a   copy of an 1887 ledger written by a P.A. Jackson: "Robert left England   with John Winthrop 1630-31 but which Winthrop is not known.  In with the   Massachusetts Bay Company, he doubtless was one of the 900 who sailed   from Yarmouth on the 7th April 1630.  At any rate the Coat of Arms of   his family was emblazoned with two greyhounds and a dolphin crested with   a mailed arm raising from a m[issal?], in the hand a tilting spear.” SOURCE: The History of Ancestor Robert JACKSON The site has a wealth of maps and other visual elements. It is well worth a visit. The primary source for this snippet was: John Winthrop, Portrait of Massachusetts   Bay Colony Governor John Winthrop 17th Century. It was held in the   Winthrop family until the 19th century, when it was donated to the   American Antiquarian Society,   http://www.americanantiquarian.org/Inventories/Portraits/153.htm ,   additional provenance from the American Antiquarian Society:   http://www.americanantiquarian.org/Inventories/Portraits/bios/153.pdf              |

Thence to Harford  Conn.  Thence to Hempstead in 1643  which was perhaps the first English settlement in the western part of  Long Island.  He had a wife Agnes.   His will dated Ref. The Jackson Family Rockaway Records Morris Co. N.J.

        Notes from Joseph Burton Jackson (1920-1962) 
        NOTE: In an email dated October 20, 2011, Jim Jackson
          mentioned:  
          
        This
          was his working document and was hand written in a notebook and still includes
          strike-overs that I am sure he would have fixed had life given him more years.
           My uncle was a very simple and down to earth man whom the Lord took way
          too soon.  Devout Christian, wonderful husband and father, clerk in a
          furniture store, talented furniture restorer, and most of all kind and gentle
          soul.    
          
        He
          was able to get this far without leaving this continent but said to go further
          he would need to go to England and dig through the old church ledgers, although
          I have read some internet documents of those who have done just that and found
          the trail ended with Anthony in England.  I suspect you have seen the same
          documents.  Apparently the church records contained a gap of 200 years.
           All things considered, I think Uncle Burton did a quite remarkable job
          considering he was a man of modest means with no internet and very little
          opportunity to travel... 
          
        The
          only thing I would ask is a little feedback on your thoughts after reading his
          work....

            Early Jackson history 
                The following information on the lineage of the Jackson
                  family is from the records of Mrs. R.V. Cordell of Lewistown, Illinois. Her
                  ancestor was Sarah Jackson Hymer (1794-1883 who was the daughter of Joseph
                  Jackson 1758-September 24, 1842 and Sarah Kirkman Jackson 1764-1877. The
                  records were in Mrs. Cordell's mothers papers. 
                
              Isaac Jackson was the first immigrant to this country. He
                was the ancestor the Jackson family in this country. His father was Anthony
                Jackson who immigrated from Lancashire England to the neighborhood of
                Carrickfergus, Ireland in the year 1649. In England they were members of the
                Episcopalian Church and took an active part in politics and some members of
                the family belonged to the Parliamentary army and by deeds of valor of which
                we are not informed, gained the right to wear a coat of arms and the devices
                which it bore was two greyhounds and a dolphin. The right to wear a
                coat of arms indicates a certain degree of rank. Isaac Jackson was born in
                1665 in Ireland. His wife was Anne Evans Jackson. They came to London Grove,
                Pennsylvania in the year 1725. They joined the Quakers in Ireland and Anthony
                Jackson was one of the first converts to Quakerism and he established the
                first “Friend’s” meeting house in 1654 in Ireland. Isaac died in 1750 in the
                86th year of his age. 
                
              Isaac Jackson had a son Thomas who married Mary Boardman.
                They had a son named Isaac the 2nd who married Mary Miller, daughter of James
                and Catherine Miller. They had several children who moved to Eno, South
                Carolina and some members of the family moved to Maryland and from there to North
                Carolina. Then comes her grandfather Joseph Jackson and grandmother Sarah
