Do you have her marriage cert to find out address at that time? Dec qtr 1878 Merthyr Tydfil vol 11a pg 599.
Their eldest child on the 1891 is Julia, birth reg
Julia Hegarty march qtr 1880 Bedwellty vol 11a pg 89
Can't see a Julia Hegarty in 1881, in the right place, but there is this family which matches for birth places and ages

John Flaherty head mar 30 labourer in iron works b. ireland
Ellen wife 28 b. Tredegar
Julia dau 15 months b. Sirhowy
Ellen Flaherty 50 laundress b. Ireland
Julia's birth cert may show address for parents?
