Ivankov and Mihawk don’t seem to have much in common but at least they have is that they both parallel Hancock
Luffy and Sanji got sent to Hancock and Ivankov the two of them coincidentally being queens of islands of women
Luffy and Zoro were sent to Hancock and Mihawk respectively. While there’s no full on confirmation yet the two are definitely related. Potentially being siblings but at worst both having moms from Amazon Lily
