Hi Pat,

This is probably not your Julia Hannah Charlotte Rennie formerly LeMaitre, but perhaps a sister (but odd both Charlotte if so):

Marriages Maughold par reg:
28 May 1903
William Daniel KINRADE, 33, Bachelor, Plumber, Ramsey, [father] Charles Kinrade, Boat owner, and
Georgina Charlotte Margaret LEMAITRE, 28, Spinster, Ramsey, [father] Francis Stephen Lemaitre (dec), Vetinary Surgeon.

30 Jan 1873
Francis Stephen LEMAITRE, Full age, Widower, Veterinary Surgeon, Ohio House, Andreas, [father] Peter Stephen Lemaitre, Farmer, and
Susan GAUDEMARD, Full age, Widow, St Paul's Sq., [father] Arthur Linton, Cabinet Maker.

Tom Corteen, who made these transcripts, didn't usually include the witnesses' names, and these look like an IOM family. Or they all moved to the IOM from Guernsey.
