This is an extract from my great-grandfather's birth certificate. The official had suprisingly nice and clear hand-writing, but I have trouble identifying the first letter in my great-great-grandmother's surname. I have reproduced the relevant section here:
The text reads:
wohnhaft in Burg, Coloniestraße No 9,
evangelischer Religion, und zeigte an, daß von der
Wilhelmine Kühne geborenen
?arl, seiner Ehefrau
The letter looks like a 'G' to me, but could be a 'H' or even a 'C'. Given that the rest of the handwriting is very neat, my hope is that this is some variant of Kurrentschrift that I'm not familiar with and there's a definitive answer to which letter it would be.
