Family Origins of Doherty (Banker).
This family can be traced back to Hugh Doherty, (1796-1871) born in Dohertystown, Aughterlin, Parish of Killygarvan (Rathmullan) County Donegal. He married Susan Sheridan(1810-1877) Kinletteragh, Rathmullan. They farmed 70 acres of land and had seven children. Hugh is listed as "Landholder" in the Tithe Applotment Records 1833. He died of "old age" (75 years) on 29th November 1871 and was succeeded by his son Charles Doherty 1844-1938.
Hugh had two brothers; Charles(big Charlie), married (1848) Sheila Sheridan, Upper Craig, Rathmullan and Cornelius (Knogher)1800-1877, not married. He also had a sister who married John Aiken, Drumherrive, Ramelton. Charles(big Charlie) received a one third, Rundale, share of the land and he was succeeded by his son Philip(b.1849).
The Doherty's of Craig, Rathmullan., were said to be cousins.

In 1834, the Ordnance Survey redefined Townland boundaries and "Dohertystown" is now part of Legland Townland situated 5 km Northwest of Rathmullan.

Nickname:
The family nickname is "Banker" and there are various explanations for its origin :

Margaret (Boyle) Doherty 1868-1961 explained that when neighbours sold animals at fairs they gave the money to "the Bankers" for safe keeping. There had been a lot of robberies in the area but Banker's was considered to be "a safe house". A book was kept where details were written down and the money would be available as and when requested.

Emanuel Boyle (1888-1990) said that they were called "the Bankers" because they were the only ones around that area with money in the Bank during the Famine of 1845 -1849.

William (Owen Rosha) Sheridan (born 1846) explained to Tommy Shovelin (1902-2003) that the "Bankers" were two brothers who returned from England with 'plenty of money' and were able to farm in a good way. They also kept money safe for locals until sufficient was saved for the boat fare to America and thus the family became known as the Bankers. The boat fare from Derry / Londonderry to Philladelphia in 1846 was £5 (five pounds).

Hughie Coyle (1897-1987) said that they saved money until they had £5 (five pounds) which was then put in the Bank. In those days the five pound note (fiver) was known as "the Banker". He said, that they always tried to save "the Banker".

Nicknames distinguished families with similar surnames living in the same area. For instance, the neighbouring Doherty family in Legland was known as "the Hugh Pheilemy’s" while our family was known as "the Bankers".
