Do

During my research I keep coming across the abbreviation Do. and something that looks like ibm., jbm., or lbm.  Does anyone know what these two abbreviations mean.

Do = dito
ibm = ibidem (latin)
 
Both abbreviations mean the same, i.e. literally the same (as above, as previously). Often used for placenames, such as the birthplace column in the clerical survey records, or in the christening records when two witnesses came from the same farm or village.

Dito is the same as ditto in English.
