My gg. grandfather was William and Anns first son, William b. 1824 who married Margery McMullen in 1846. They had 8 children and their daughter Elizabeth b. 1859 married William Bury Lane in 1880. They had 10 children and their daughter Louisa Marjory b. 1889 married my grandfather William Robert Dean.
I dont have many details on William and Anns decendants and would love to know more about your John.
If you are interested I am quite happy to share info.
Looking forward to hearing from you,
