Despite this coincidence, I do not believe they are related. Taskmaster is commonly an Avengers villain, and Alicia Masters is an ally of the Fantastic Four. If they were related, Marvel would probably have made them have ties to the same team. For example, Alicia's step-father is an FF foe. Also, on both their pages on this wiki, they are not said to be related. However, this could still be proven by Marvel. After the whole Magneto not being the twins father thing in AXIS, I think Marvel can do whatever they want with families.
