It probably doesn't help you much, but the following appear in Brian Lawson's Manx Census index for 1891:
Eleanor A. Crelling age 19 Bride Parish, District 3, Entry 30, born in Bride
James Crellin age 52 Bride Parish, District 3, Entry 32 born in German
Margaret A. Crellin age 55 Bride Parish, District 3, Entry 32 born in Andreas
It is possible these are the same people living near one another. Eleanor could easily have been born in Bride and Christened in her mother's family church in Andreas.
Eleanor is likely to have married within a few years but you could try the 1901 census on-line at www.census.pro.gov.uk - you never know! I had a quick look but could not see any obvious candidates for your Eleanor.
You could try contacting the Manx General Registry and ask them to search for her wedding or death between 1891 and 1901 - I do not know what they would charge for this, but a copy certificate itself only costs about £5 sterling.
