Cockney nicknames

In the old days Cockneys - at least my Victorian Cockney ancestors- were all known by a nickname . My great uncles for example were known as Speck ,Missel and Banger . I was dubbed Topsy by my grandfather when I was born, and he always used it. I was told this was to protect Cockneys from the Law should they be in trouble . Anyone else known by such an alias ??
