Have transcribed an entire marriage document except for what the maiden name is of my GGG-Grandmother. The marriage record is from Edinburgh, Scotland, 1861
Left column is residence: No 13 Blackfriars Wynd Edinburgh
Right column are the groom's parents: Laurence Keenan Labourer deceased and Margaret Keenan MS

?? also deceased.
I would appreciate any assistance with the maiden surname.
