You haven't given quite enough information for us to help you.
Remember that we're not all geneticists here ... can you give a little
bit more context? Are you trying to estimate pedigrees, or populations
of origin, or ... ? Another way to make it clearer would be to present
the code you used to generate the "data" (it sounds like you did this
in R). (The mle function from stats4 provides a *framework*
for maximum-likelihood estimation; you still need to be able to write down
a function for the likelihood of a given set of parameters.)
