Hello Marj,

Was your grandfather Frank Stanley Duggan who married Esther Cath. Gawne 16 Nov.1899 in Malew? He was from Arbory; she was from Malew.

You can see a scan of the original record here, which gives a lot more details:
familysearch.org/ark:/61903/3:1:3QSQ-G9Q6-NF1J?mode=g&i=242&cc=1784428

If not the correct couple you need to give more details - there are many "same name" couples in the IOM, so to find relatives you need to give forenames and dates.
