make an anonymous pair to iterate over.
foreach(var pair in parcels
.Where(p => p.Owners != null)
.SelectMany(p => new { o = p.Owners, p })
.OrderByDescending(x => x.o.RecordingDate ?? x.o.SaleDate ?? x.o.DateEntered)) {
var owner = pair.o;
var parcel = pair.p;
// do stuff
}
// alternate syntax
foreach(var pair in from p in parcels
where p.Owners != null
from o in p.Owners
orderby o.RecordingDate ?? o.SaleDate ?? o.DateEntered descending
select new { o, p }) {
var owner = pair.o;
var parcel = pair.p;
// do stuff
}

You'll need to add the parcel to the item returned by SelectMany:
parcels
.Where(p => !p.Owners.IsNullOrEmpty())
.SelectMany(p => p.Owners.Select(o => new { Parcel = p, Owner = o }))
.OrderByDescending(x => x.Owner.RecordingDate ?? x.Owner.SaleDate ?? x.Owner.DateEntered)
.ForEach(item =>
{
Parcel p = item.Parcel;
Owner o = item.Owner;
...
}
