I am looking for help tracing ancestors of my great-grandfather, William Jardine, b1879 in Banbridge. Father James Jardine- possibly a farmer, mother Sarah Marshall. William moved to Rothesay, Isle of Bute around 1900. Siblings were Sarah, Ellen, Jane, John, Margaret and Thomas. John may have continued farming with his father, James according to census. Sarah Marshall died around 1890- I can't find anything about her parentage, or where she was born.
James Jardine/Jarden parents possibly called James and Margaret- all Presbyterians- did they have other children.
Grateful for any help- thank you
