Hi Julie: In Ireland the name was MacLochlainn from the O'Naill "sept" later the O'Neills. Name starts to change around 1500 to MacLaughlan/McLaughlan. Late 1590's to 1610 many changed the spelling to Macklin due to the fact that in order to keep yout job/get a job or lease or tenancy on land one had to be either an Anglican or Presbyterian. Hence the wholesale change of a lot of names including the dropping of the "O" - O'Leary became simply Leary etc. This is the process that Charles MacLaughlan/MacLochlainn went through as he travelled from north west Ireland down to Londonderry and eventually to London especially if you wanted leading parts and wanted to perform in Elizabethan theatres which had their leases from the Crown. As for Macklam there were a few instances where the name was changed to Macklin when they [Macklam] immigrated to Oz and NA. The precept where your mother or grandmother kept her maiden name is not that uncommon as many women, even to day. will recognize the economic value of having a better postioned surname than that of the spouse. There are a number of instances where eastern Europeans (especially Jews) have changed their name to either fit in or again to re-position there families in terms of the prospects for their children to fit into the general melieu. Any way you are who you are, and we are only as good as the current generation. Be well.
