This interesting and unusual surname is of English locational origin and is a dialectal variant of the name "Hartsop", a parish and village in Westmorland, five miles north-east of Ambleside. The placename itself probably derives from the Old English pre seventh Century words "heorot", stag (medieval English "hert.") also a nickname for someone bearing a resemblance to a stag, and "topp", top, hence "Stag's top", the top of Stag's hill. The following examples illustrate the name development, recorded in the church records of London mention Joan, daughter of Thomas Hartoppe, christened at St. Vedast Foster Lane and St. Michael Le Querne on April 22nd 1582. At Fowey in Cornwall, Mary Hurtop married Thomas Williams on May 17th 1591. Richard, son of Henry Hartupp was christened at St. James Clerkenwell, London, on January 12th 1612, while at St. Mary Magdalene, Canterbury in Kent, Joseph Hartop married Anne Dunnye on January 23rd 1625. Sir John Hartopp, third baronet (1658) became M.P. for Leicestershire (1678-1681), and was also alderman of London and in St. Cuthbert's, Bedford on Thomas Hartropp married Ann Fairey on October 12th 1857. The first recorded spelling of the family name is shown to be that of Jane Hurtipe, which was dated August 26th 1576, married Thomas Johens at St. Margaret Moses, London, during the reign of Queen Elizabeth 1, "Good Queen Bess", 1558 - 1603.
