[8] Crookall became a leading member of the Isle of Man's Freemasons Society and was Master of the Tynwald Lodge.

Crookall paid a second visit to North America when along with 22 other representatives from the Isle of Man he attended the Manx Convention in Cleveland, Ohio in August 1928.

[9] Following Crookall's death, his widow became Honorary President of the NAMA and oversaw a further "Homecoming" in May 1937,[10] and attended numerous conventions in North America for the rest of her life.

This was required to reduce congestion at the junction of the Victoria Pier and the promenade and provided welcome employment for many of the town's men over the lean winter months.

[13] He also took a keen interest in Noble’s Hospital, and founded, in memory of his first wife, the Jane Crookall Maternity Home.

The maternity home remained in use until 1992,[14] today it is Crookall House, the HQ of the Department of Health and Social Care.

Crookall was also instrumental in the erection of the Douglas War Memorial, contributing the highest personal donation towards its construction.

[16] Additionally £2,000 was set aside out of the Residual Trust, the income on which continued to provide the poor children of Douglas with presents at Christmas.

[17] Crookall was a strong supporter of the establishment of a supplementary race meeting on the Isle of Man to be held for amateur competitors, to be run over the existing Snaefell Mountain Course and to serve as a backup in case the Auto-Cycle Union decided to transfer the TT Races to England - which in the early 1920s was a distinct possibility.
