Hello there Rootschatters, I am stuck

I would like to find out what become of 3 people. They are
Ann Jane Jones- b abt 1890, Llandyrnog, daughter of Robert Jones- b 1857, Llangynhafal, d 1931, Llandyrnog and Elizabeth {Williams} b 1862, Aberwheeler, d 1927, Llandyrnog. This family lived on Fron Vox farm.
Thomas. A. Jones- b abt 1900, Llangynhafal, son of Robert Jones- b 1870-71, Llangynhafal, d 1901, Llangynhafal { I think } and Hannah b abt 1879 at Llancilldar. This family lived at Tyn Y Caeau farm near Gellifor.
If the second Robert died 1901 then it is quite possible Hannah would remarry.
The two Roberts would have been cousins.
Thanks Bob
