Here's their e-mail address for the civil registry, civil@registry.gov.im , to get the info on cost of certificates and their mailing address.

In trying to help, I found another Jelley/Jelly with the middle name of 'Colquitt', a Henry Colquitt Jelley, son of a Robert Andrew Joseph Jelley. I don't know if it just coincidence or could there a connection? I'm wondering, given the Manx naming patterns, if Henry Colquitt Jelley, might have given a son the name "Robert" in honor of his father, and then gave the son his middle name of "Colqluitt?"

Below is what I've found on-line.
**************************************************************************************************************************
On Family Search "Isle of Man, Births and Baptisms, 1821-1911, " there is a Robert Andrew Joseph Jelly, christened 14 May 1867 at St. Barnabas, Douglas, IOM, son of a Richard Jelly and Jane.

From Manx BMD, Robert Andrew Joseph Jelly married in Braddan, IOM, in 1887- Page 211, Registry: COE.

Again from Family Search "Isle of Man, Births and Baptisms, 1821-1911, " on 13 Mar 1895, Douglas, lOM a Henry Colquitt Jelley, was born to a Robert Andrew Joseph Jelley and Eliza Jane Corrin.

According to Manx BMD, Henry Colquitt Jelley died in 1970 at age 74-Dist. Douglas, Vol, 59, Page 5481.
