Neilson's roles also included the title role in Kester's adaptation of "Dorothy Vernon of Haddon Hall" (1907). Neilson's and Terry's productions continued to favour historical romances or comedy melodramas, including "Henry of Navarre" by William Devereux (1909 at the New Theatre). "Henry" and "Sweet Nell" became their signature pieces during many tours of the British provinces and during their US tour in 1910. They also produced and starred with much success in "For Sword or Song" by Robert Legge and Louis Calvert (1903), "Dorothy o' the Hall" by Paul Kester and Charles Major (1906), "The Popinjay" by Boyle Lawrence and Frederick Mouillot (1911), "Mistress Wilful" by Ernest Hendrie (1915), "The Borderer" (1921), "The Marlboroughs" (1924), and "The Wooing of Katherine Parr" by William Devereux (1926). They also starred in "A Wreath of a Hundred Roses" (1922), which was a masque by Louis N. Parker at the Duke's Hall to celebrate the Royal Academy's centenary. In 1926, Neilson starred alongside Lawrence Grossmith in a revival of "Henry of Navarre", which toured the provinces. She later starred in "This Thing Called Love" in 1929.
