This thread has got me curious again ... I just checked into GR, and found this as 'Hot Matches' with my family ...
John Williams 1834 Wick, Gloucestershire
Florence Monk 1922 Edmonton, London
Alice Chadwick 1910 Old Waterfoot, Haslingden, Lancashire
George Tidswell 1909 Haslingden, Lancashire
Frances Allen 1861 Parowan, Iron, Utah, USA
Henry Williams 1889 Chewton, Keynsham, Somerset
I DO have a John Williams ... but he was born in 1839, in Dorset
I DO have a Henry Williams ... born 1883, in Hampshire
But who are the rest of these people ? I have no idea how the GR programme works, but to give me six people I've never heard of as people on MY tree ... is amazing, and frankly, quite annoying and time wasing.
