More McGREGORs

Even more HENDERSON/McGREGOR activity last 2 days. I presume we might find them all sooner or later!
Latest main discovery was finding that Helen (aka Nellie) McGREGOR married an Andrew JACK (ta Linda). I then found that this family emigrated to the States in 1907 (Andrew) and 1908 (rest of family). This added in a BORRUP line. Main haunts seem to be New Jersey and Connecticut, with a dash of California and Florida, this latter assuming that the Margaret Elizabeth Addison BORRUP who is shown as dying in Miami in 1948 is Margaret E A JACK dtr of Andrew and Helen/Nellie.
A Rootsweb WC "tree" of the BORRUPs has the JACK family a tad mixed up, but is full of useful hints as to where to look for assorted branches, and it looks like there's a NZ connection in there too, not that I can figure out where Elsie ALLER fits. Anyone out there to help me on that one?
Brenda K, (married to a grdson of George Manson Henderson BAIN), pointed me to a searchable site for British Columbia burials.
