My one name study started, like many others, with my own personal research into my maternal grandmother's ancestry. She was a SENNETT, born in Normanton, West Yorkshire. My mother remembered visiting her relatives in Normanton as a child, and being aware of the large numbers of relatives in Normanton. I quickly became aware that most of the SENNETTs in Yorkshire appeared to be related and started collecting all references to the surname there. As well as the Yorkshire SENNETTs, I noticed that several other areas of England also had significant numbers of people with the same surname, and I wondered if they would be able to be linked at some point. It also interested me that the family in Yorkshire were miners who had come from Avoca in Co Wicklow, Ireland, and I wondered if they would connect to the much larger group of SINNOTT of County Wexford.
In 2011 I registered the SENNETT one name study and began to more formally collect up further references and reconstruct families starting with English records.
By 2015 I had also made significant progress with North American, Welsh, and Australian records and identified some instances of the name in other countries (New Zealand, South America).
Currently the main focus of the study is on Irish records and, in liaison with other researchers, the early history and origins of the name from its 12th century arrival in Co Wexford.

(please see http://www.britishsurnames.co.uk/surnames/SENNETT/ for up to date data).
Frequency of the SENNETT surname from the above website was about 8 per million people in 1881 in the UK, and about 11 per million in the UK now. In the US, current frequency is about 7 per million, with about 3 per million in Australia. In spite of the Irish origins of most of these, there are very few people in Ireland using this spelling.
Frequency of the SINNOTT/SINNETT surnames appears to be slightly higher than SENNETT, and SYNNOTT slightly lower.
The main study database is a family tree database (Legacy) containing over 60,000 records, most of which are linked into multigeneration trees.
Information has been extracted from a large number of (mostly online) databases and includes: Census; civil and parish birth marriage and death records; cemetery records; newspaper records; immigration documents; military and occupation records, etc.
Data is collected from all geographic regions where the study surname is known to be found.
