My ggrandmother Mary Ann Pernie (b. 1845)had a sister Anna Maria Pernie (b. 1860)both born in Ulverston. Anna Maria married Albert Wood and lived in Barrow in 1891. I have names of three children: Ellen (b. abt 1884), Elizabeth (b. abt 1887) and John Pernie Wood (b. 1889). Your grandfather was probably the next born. Happy to compare notes.
