This all needs further scrutiny to confirm but this is what I've uncovered so far:
Annie Guest b. c1872 married George Smith b. c1868
Annie Guest daughter of Thomas GUEST b. c1823 & Elizabeth MORGAN b. c1827 (daughter of William MORGAN)
Thomas GUEST b. c1823 son of Thomas GUEST b. c1789 & Ann JAMES b.?
Thomas GUEST b. c1789 son of Richard GUEST b. c1743 & Joan BEVAN b.?
Richard GUEST b. c1743 son of Richard GUEST b. c1701 & Sarah Long b.?
Richard GUEST b. c1701 son of John GUEST b.? & Elizabeth ? b. ?

I've found 2 marriage entries for a John GUEST to Elizabeth's one from 1690 (Elizabeth GULLIAM) & one from 1697 (Elizabeth Mountjoy). Plus a baptism record for a John GUEST on 14 May 1665 so at the moment the trail ends there.

Thanks for the help
