I think I may be related to Kate Callaghan, wife of James Wigmore. She may have been a sister of my g-g grandmother Julia Callaghan. Their father was Patrick Callaghan. At the time of the 1911 census, Kate was a widow and I suspect that there may not be any descendants of this branch of the Wigmore family. Kate listed 5 children born and 3 still living. Those still living were probably Ellen Mary who did not marry, and James and Stephen -both priests. Her son in law was also a widower as Kate's daughter died having given birth to only one daughter, Mary Josephine Culhane, who also died of double pneumonia, aged 17. If anybody is familiar with the history of this family, I would be extremely grateful to hear from you.
