Robert Lace (1805-1869) first married in 1844, Lonan to Eleanor Fargher (1816-1848). They had two children: John chr. 1846 & Ann (1847-1854).
Robert Lace then married Esther Caine 1857, Lonan. Their children were: Robert chr. 1858, Isabella chr. 1860, Thomas chr. 1861 and Mary Ann born circa 1866. All dates are in Lonan.
Robert Lace left a will in 1869 which should tie everything together.
I haven't researched Esther Caine's background so not sure where she was born.
