Wondered if "Tregaen" was an attempt to capture "Tregaian " (Llangefni)?
Hi looking at the possible baptsms of Elizabeth and Hugh, I initially thought yes this must be a good chance of being her, Owen appears to have died prior to 1841 census, as this appears to be some of the family in Church Street, Llangefni :-
Elizth Rowlands 40
Hannah 15
Ann 15
Elizth 8
HO107/1360/ 8/4 / 1
1851 census :-
Elizabeth Rowlands 50 Widow occ Mangler b Amlwch
Hugh 16 b Tregaian
Thomas Phelps 2 Grandson b London
Elizabeth Phelps 3 Granddaughter b London
Residing Church Street, Llangefni
Census ref HO107/2520/30/15
It is in 1861 when Elizabeth snr states she is a Mangler widow of Agricultural Labourer
Residing Church Street, Llangefni
Census ref RG09/4362/51/9
