Redda, I searched for Sarah wife of Thomas Burt. I posted this about 7 years ago.
I am looking for information, (and any methods ) regarding my ggg grandfather william Williams, a miner, born about 1798 in Cyffylliog, Denbighshire. (so says the 1851 census). He married Jane (maiden name unknown), and had at least 4 children. Ebenezer ( my gg grandfather b 1842 Dymeirchion ),John Williams ( b 1840, Dymeirchion) and Jane Williams (b,1835 Newmarket) and Margaret Williams (b. 1833 Newmarket).
The 2 girls seem to be in Liverpool in 1861 as a niece to Thomas and Sarah Burt. Sarah was born in Dymeirchion about 1810.
I do not have ancestry.com anymore, but you may have solved my Jane Williams history. I am a little out of touch with this search from 7 years ago. but I obviously, at the time, found the 2 Williams girls with Thomas and Sarah Burt in 1861 as nieces. If they are nieces, then a good chance Edwards was Jane's (b 1799) maiden name. especially since Sarah is from the same area (Dymerchion/Tremerchion)
If you have any other info, I would appreciate hearing from you. If you have ancestry, I would love to see copy of this entry in 1861.
