Yes, JB stands for JEan-Baptiste.One has to rely to shorcuts at times.
In gen. research, we have gone past the Loiselle index cards given that we have much better databases.I have used BMS2000. I have have no personal interest in it but here is a description that I have prepared given the number of times I have had to propose it to people I was in contact with.
Quote BMS2000 basic instructions.
BMS2000 is a database of baptisms, marriages and deaths («S« stands for «sepulture» or «burials») records for the province of Quebec, a little from Ontario.The data were taken from parish or counties repertories.English and French versions of instructions are available. More marriages than B and D because B- and D repertories were produced for no more than 10 % of the Quebec parishes and few or none from the Montreal area.Given that the data are taken from repertories, one has to be aware that if the repertory was produced in 1980 and for which there has not been any update, the marriages for the post-1980 period are not available in BMS2000.To make up for it, we in Quebec use the marriage and deathdatabase of the Quebec Statistics Bureau or Statistics covering the period of 1926 to 1996.Now avail. on line.Register if you want to make research in Quebec.25 free queries.Thereafter, you may deposit some funds.about 10 cents per query.No charge if you do not get the full details of the record.I suggest that you search with surnames of the couple only (no given names).If the surname of a partner has numerous variations, use the surname of the other partner and one or two given names (bride and groom).Rather easy to use. To search for a marriage: select: SPOUSES (in the upper right corner section).If you want the name of the married male children of a couple, select: GROOM's parents and insert the parents' surnames and given names .To get the names of the married female children of a couple, select: Bride's parents (because when the daughters of a couple get married, they are brides), and insert the parents' surnames and given names.May sound complicated but it is not after a few attempts. Unquote.
Phonetically, it appears unusual to go from Bourgault to Bushroe but it may be a lead.How good a match do we have in terms of timings?
If this is the right couple, there is a lot more data avail. on BMS2000 and other research instruments.If you have problems with BMS2000,I will try to help.
