I have some difficulty with these relationships.From the Solohead and Oola Parish Records I have that ROBERT GUBBINS married LUCY KIRBY probably between 1800 and 1809 and they subsequently had 6 children: EDMUND - born 1810/11 married 1838 MARGARET O'BRIEN JOSEPH - born 1812 married 1839 MARY KEATING MARGARET - born 1814 married 15 Feb. 1836 JAMES KEATINGand died 28 April 1886 ROBERT - born 1816 WILLIAM - born 1818 and died 9 Jun 1876 FRANCES - born 1820
The only JOHANNA of this family is the youngest child of JOSEPH and MARY nee KEATING, born 1849.
I have no record of a ROBERT GUBBINS marrying a CATHERINE FITZGERALD.
I have a JOHANNA GUBBINS born 28 August 1837 of JAMES and MARY nee COMBA of Limerick City, but her brothers were JAMES and JOSEPH.
This later information came from a member of the Gubbins egroup.
