The turnout on 5 May was 52%, with 785 votes cast from an electorate of 1,507.
Councillor Rose polled 343 votes, followed by the Liberal Democrats' Monty Stuart-Monteith with 274, Labour's Andrew Mellodew Hartley with 132 and the Green Party's John Gary Ward with 34. There were two spoiled ballot papers.
After the declaration at Kniveton Village Hall just before midnight on Thursday, Councillor Rose said:
"The reason we're all here is obviously because we lost my wonderful husband Lewis and if I can in any small way emulate what he has done over 47 years I will be very proud. I will do my best for everybody."One of the region's leading political figures, Councillor Lewis Rose was the longest serving councillor on the Derbyshire Dales council and the last serving founder Member of the authority. He was Leader of the Conservative group for 45 years until 2019.
He became a member of West Derbyshire District Council on its formation in 1974 and held the distinction of proposing it be renamed Derbyshire Dales in 1988. For most of his time on the District Council he served as Leader or Deputy Leader of the Council.
