Ruth, You may already have all the following information, but just in case you haven’t....
I looked at Ancestry trees relating to an Edward Taylor b in the 1820s in the IOM, and I found much misinformation (eg trees which name the Edward Taylor b 1827 of Crossack Malew, son of John Taylor and Eleanor Kermode, and wrongly state that he was the ET who married Ann Clague). In particular, I found that, of the trees which had the correct second wife for your ET (Elizabeth Morris, widow, nee Cordon), they either had no name for ET’s first wife or didn’t refer to her at all.
I guessed that it might be a difficult search since the first wife married and died between the 1851 and 1861 censuses. The marriage was easy enough---Jane Cannell m 1855 Braddan --- but the children were trickier. I only found 2 of the 3 children’s baptisms:
Child from first marriage (should be Taylor):

The third one came to light from the following headstone inscription:
Photo from findagrave via familysearch:
Toxteth Park Cemetery
Section D, Grave 222
(close gap between ht and tp)
“Sacred to the memory of / Jane / wife of Edward Taylor / shipwright / who departed this life January 26th 1860 / aged 35 years / deeply regretted by a large circle of friends / also Emma Jane daughter of the above / who died July 8th 1857 aged 3 months / and was interred at St Luke’s church / Kirk Braddan Isle of Man / also Eleanor Elizabeth / daughter of the above / who died July 31st 1859 aged 4 months.
The photo was added to the website as recently as last year, so you may not have seen it.
While you’re on your trip to the IOM, you could look for Emma Jane’s headstone at St Luke’s ---- perhaps someone on this message board could look up a grave reference for you.
