The transcripts of the 1881 + 1891 census I emailed to you(have you received them? any questions on info? answer privately) will tell you your grandfather's (John Thomas Burgess) family of that time. Compare his age, place of birth and parents with any information on any birth - marriage certificates you have. The 1891 clearly shows New England as their address and you know that is where they lived. Use the free bmd website for later marriages, births, deaths. After about 1912 for births, the maiden name of mother is listed. I have Edith's line as proven by certificates.
