Folks - certainly good hunting today!! We've got the right Marshall girl anyway but don't know about Alexander Thompson yet. I searched PRONI covenant some while ago and found 3 Elizabeth Thompsons (of course) - 2 in Limavady and 1 in Bovevagh and 2 Alexanders from Limavady - heigh-ho.
Philip for Ohio send me a copy of a letter which seems to prove that Elizabeth and Alex had at least one issue - a possible son called Andrew (and maybe an Edward?). As they married in 1894 we are looking at a dob of about 1895 onwards and no later than 1920 because Alexander died then (so aged anthing from 112 to 87?

?). Would either of you be able to search anything else.
James Thompson is in my family tree and somewhere I think I have seen the name Jane Arbuckle. I have 2 Jane thompsons died as follows:
Jane died 1943 aged 80
Jane died 1928 aged 40
What do you think aghadowey?
Wendy - this might be the right Alexander (or your other brother???)
Regards
Betty
