"...[inherited property] represents a contribution made to the welfare of the family by one of the parties to the marriage. The judge should take it into account. He should decide how important it is in the particular case. The nature and value of the property, and the time when and circumstances in which the property was acquired, are among the relevant matters to be considered. However, in the ordinary course, this factor can be expected to carry little weight, if any, in a case where the claimant's financial needs cannot be met without recourse to this property."
