What is the meaning of maria claras song by dr Jose rizal?

I was only able to find this English transation of it and wonder if there is a story behind this poem ... I would like to know who Maria Clara is. Without the full knowledge of the inspiration for this poem my interpretation will be somewhat lacking in depth.

However, on this initial reading it appears to be eulogising the importance of one's roots, of one's homeland, using the analogy of the bond between mother and child. The poet, whilst professing love of his country (incorporating the need to have a place of one's own in which to die as well as to live), expresses his sorrow for those not having such a place ... a Motherland of their own. The overriding theme is 'Home Sweet Home'.
