For the Linguaphiles - Cape'in / Capelin / Capeƚin

At the family reunion in Italy we were being told that our name was pronounced Capelin (three syllables with equal emphasis all three syllables) and/or Cape'in. The locals insisted in pronouncing it in two ways one of which dropped the L which was very confusing. Well now I understand.
Cape'in is the Venetian pronunciation.

I've been searching for some Venetian vocab to use in my
book and yesterday came across a site devoted to the Venetian Language -
alphabet, pronunciation, dictionary etc all in English.

I had found a word that I wanted to use but it had this strange symbol in it ("ƚ" ) - so I was searching to find out how it would be pronounced and ..........

There are two versions of L in Venetian. One is the standard L of English and the other ("ƚ" ) with a line through it, has a sound which is described as between L and E (see below). So the Venetian spelling of our name would have been Capeƚin, the "ƚ" pronounced like a very breathy (aspirated) "hey" or perhaps an aspirated "ee" - Cape'in. Here's an exerpt from the Venetian alphabet and pronunciation website:

l		same as English, "l" as in "lean", "lamb"
ƚ		typical Venet, semi-vowel, pronounced between a full L and an E (without the tongue touching the palate)

Also in Venetian the "a" is pronounced as the "u" in "gut" so phonetically possibly Cup/hey/in or Cup/el/in rather than Cap/hey/in or Cap/el/in
