Looking for parentage of Michael Ford born 1807 Ballinrobe, County Mayo, Ireland and died c1867 NSW Australia.

Michael served in the 39th Regiment Foot under Lieutenant General Sir George Airey. He joined the Army on 11th July 1825 aged 18 and was discharged unfit for duty on 23rd June 1846 due to being wounded in the chest.

Michael married Harriet Salisbury on 20th April 1835 in India.

Also looking for Harriet's parents as they are suppose to be Lord Salisbury and an India Princess. Have tried looking up this Lord Salisbury but to no avail that earlier in the 19th century.

Hoping some kind person could look up either military, bdm, pension records or birth records as Harriet was suppose to be born c1822 in Dinapore, India.

Thanks in advance
Tracy
